[PHP-DB] Re: [PHP] reading a URL...
Here's the mail I sent yesterday right after your question. I sent it to the general PHP list (you posted it there). But obviously your never read that list. Don't post any questions there then. There are people putting time in answering your questions, so you have to make sure they don't do this for nothing. Post your questions only to lists you actualy read!!! Anyway, I had already answered your question, so here's that answer. This is the quickest, easiest and most common way of using the variables you get by GET or POST: Just use $id in your code. That should do the job. Variables that are passed using GET or POST you can just use in your code. Ofcourse you have to add the $-sign. So if you use the URI: http://www.arandomsite.com/news_story.php?id=123 You can just use: "SELECT xxx FROM yyy WHERE id=$id" RenzE.

Re: [PHP-DB] Indexing help
replies below: ""M. Verheijen"" [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Dear reader, A newbie mysql/php-question here! I've filled a mysql-database with about 1600 records. All these records contain items which are on sale on a website. Every row contains an integer defining the category to which a item belongs. At the left of the website there are buttons linked to a php-page which does a selection like this: select * from PRODUCTS where SUBCODE = \"$SUBCODE\" As you might have guessed, every button is a link in the form of: a href="products.php?SUBCODE=8"img src="../button2.gif" border="0"/a This all works well, but now my questions! Is it wise to make an index for the integer column? I assume it is because it's the row almost all queries are using in there where-statements. What kind of speed increase can I expect, will it increase the speed of query's if the workload goes to 2000 queries a hour? What's the best way to make this index, how does it works. i always work on the theory that i index columns that i use in the select section of a query, or a where. keys will be indexed automatically (AFAIU). the speed increase will be dramatic. i used postgres and didn't index a field (accidently) and then ran queries.then indexed it and the speed increase is huge. as for making indexes it depends what tools you use. most tools such as mysql-admin etcc will let you create indexes by a pointy clicky interface. true purists might insist on: CREATE [UNIQUE] INDEX index_name ON table [USING acc_name] from the sql command line. I've read about the use of indexes in the mysql-manual and phpbuilder.net, but both are kind of short and don't tell what you're doing exactly. Anybody of you have some pointers to good webresources about indexing. i don't think you need to get into what particular type of index it is (hash, etc) but they are generally a good thing. Yes, I know a long list of questions ;) I hope that some of you can give me a clue or two. log lists of questions are a good thing and should be warmly welcomed by everyone.

[PHP-DB] get_browser()
hi all
how does everyone feel about the get_browser function?? Is the general
impression it's overkill, and also flawed since it depends on the
browser.ini file being up to date, or it is widely used?
I'm about to need to use browser detection I'm wondering if a simple
get_env("HTTP_USER_AGENT") will be far simpler

[PHP-DB] Re: How to print last row in an array using WHILE?
What you are missing is the first row, not the last row.
To explain:
mysql_fetch_row() operates with an internal pointer which moves one step
down the result set with each call to the function. The first time it is
called, it returns the first row, and moves its pointer to the second row.
The second time it is called, it returns the second row, and moves its
pointer to the third row. And so on. When it gets to the end, it returns
false.
Your while() structure is exactly what's needed to iterate through the
result set. But because you call mysql_fetch_row() once before starting
the while loop, the first row disappears. When the while loop starts, the
internal pointer points to the second row.
So just remove the first mysql_fetch_row() call, and it should work fine.

Your problem is probably on a line above this one. Because this line
should be valid. I do stuff like this all the time and it works
without any problems so far.
?php
// First of all, I use a variable to hold my sql statement:
$sql = "select * from $tablename";
// Then perform the query:
$result = mysql_query($sql, $db) or die("$sqlbr".mysql_error($db));

This allows you to see the sql that is actually being executed, and you
also get to see the actual mysql error.

Subject: [PHP-DB] Editing DB entries via form
What I have is an extremely scaled down version of a news DB.
What I am not experienced in doing is the following:
I want to have a page, say 'myEditNews.php'--and it will list
the news items in the database with a checkbox and an edit button.
The check box will be used for marking news items to delete.
The edit button is obvious :).
HOW:
Say a person checks the 1, 5, and 9 check boxes and hits
delete. How do I know in the myEditNews.php file that those
particular boxes were checked?? When I figure this out, I
will use a loop to delete the news items one at a time from
the database (unless there is a better way).
My understanding of check boxes is that they are not sent
from the form unless they are checked.
Here's what I have so far:
1) Use hidden fields as flags. All hidden fields have same
name so that when they are submitted to PHP they go into an
ordered array.
2) The corresponding checkbox fields will be checked. The
value of the checkbox will have the news item DB primary key
ID to delete on.
for(i=0; odbc_fetch_row(...) != false; i++)
{
echo "input type='hidden' name='newsItem'
value='0'input type=checkbox name='newsItem".i."'
onClick='javascript:if(document.myForm.newsItem[".i."].value
== 0) { document.myForm.newsItem[".i."].value = 1 } else {
document.myForm.newsItem[".i."].value = 1; }'";
}
Am I making this hard on myself? I have seen it done, but
now that I want to find an example these sites escape my notice.
Any help is appreciated,

Re: [PHP-DB] Hold that insert!
I have the insertRecord function which is supposed to be called only
when you hit submit. For some reason I'm blanking out on how to do
this. The function and function call ARE on the same page. I think I
just need some logic to indicate "stop" and "go".
Every form has a submit button right? Submit buttons are form elements
(whose value is submitted when the button is clicked), just like any other
form field. So I have something like this:
INPUT NAME="submit" TYPE="submit" Value=" Click Here! "
In my PHP code, I check the value of $submit; if it's empty, I know the form
data hasn't been submitted yet (if it had, $submit would have the value "
Click Here! "), so in that case I display the form. If it does not have an
empty value, the user has clicked the submit button, so I can go ahead
processing the form data. Like this:
if ( empty($submit) )
{
### Display the form
}
else
{
### Do some checks to make the the data is OK
### Do the Insert, or whatever else is to be done
}

Re: [PHP-DB] Indexing help
Columns used in the WHERE clause is the good identifier for which columns to index. You don't want to index every column you select. Typically adding indexes decreases insert performance. The more indexes the slower inserts operate, because the indexes also must be updated. Adding an index to a column which is used in a where clause can dramatically increase table row selection. The database server does not have to scan the full table, instead it can use the index to lookup which rows to return. On small static tables the performance gain can be nominal. Larger tables where there are a lot of rows to check for a match, will see the largest performance gain. Think of a dictionary. You already know the index: words are alphabetically sorted. Just think if it wasn't, you'd have to look at every word to see if you've got a match. Without indexes, that's what the computer has to do. The computer (dbms) picks which index to use based on whats column in the where clause. Order By clauses can also benifit from an index. -Joe ""Steve Brett"" [EMAIL PROTECTED] wrote in message 99pjr2$20s$[EMAIL PROTECTED]">news:99pjr2$20s$[EMAIL PROTECTED]... replies below: ""M.

What kind of speed increase can I expect, will it increase the speed of query's if the workload goes to 2000 queries a hour? What's the best way to make this index, how does it works. i always work on the theory that i index columns that i use in the select section of a query, or a where. keys will be indexed automatically (AFAIU). the speed increase will be dramatic. i used postgres and didn't index a field (accidently) and then ran queries.then indexed it and the speed increase is huge. as for making indexes it depends what tools you use. most tools such as mysql-admin etcc will let you create indexes by a pointy clicky interface. true purists might insist on: CREATE [UNIQUE] INDEX index_name ON table [USING acc_name] from the sql command line. I've read about the use of indexes in the mysql-manual and phpbuilder.net, but both are kind of short and don't tell what you're doing exactly. Anybody of you have some pointers to good webresources about indexing. i don't think you need to get into what particular type of index it is (hash, etc) but they are generally a good thing. Yes, I know a long list of questions ;) I hope that some of you can give me a clue or two. log lists of questions are a good thing and should be warmly welcomed by everyone.

RE: [PHP-DB] Hold that insert!
Click Here! "), so in that case I display the form. If it does not have
an
empty value, the user has clicked the submit button, so I can go ahead
processing the form data. Like this:
if ( empty($submit) )
{
### Display the form
}
else
{
### Do some checks to make the the data is OK
### Do the Insert, or whatever else is to be done
}
I do something similar. However, my layout is like this:
--
if( isset( $submit )) {
errorChecking();
if( $noErrors ) {
doDBInsert();
header( "location: blah" );
exit();
} // end if( $noErrors )
showErrors();
} // end if( isset( $submit ))
displayForm();
--
This accomplishes a few things:
* The code is easier to follow
* If there is an error in the form, the errors display and the
form re-displays. There is only one section of code that deals
with the form, not two as there would be in an IF/ELSE situation.
But then, this is just me. :)

Re: [PHP-DB] get_browser()
Is it easier to update every web page you code with
get_env("HTTP_USER_AGENT") ; or easier to grab a new browser.ini file?
""Simon R Jones"" [EMAIL PROTECTED] wrote in message

hi all
how does everyone feel about the get_browser function?? Is the general
impression it's overkill, and also flawed since it depends on the
browser.ini file being up to date, or it is widely used?
I'm about to need to use browser detection I'm wondering if a simple
get_env("HTTP_USER_AGENT") will be far simpler

[PHP-DB] Multiple rows for one column in a MySQL table?
Hi, Is it possible to have multiple rows for one column of a MySQL databes? and if so how would I insert another row into the column in question? eg: idNamePhone Number 1Kev 123123 2John 234234 345345 3 Paul 789789 Thanks, Kev.
Re: [PHP-DB] Hold that insert!
I like your simplicity and straightforwardness.
My code tends toward:
switch($submit) {
case: "Accept":
.. insert record
break;
case: "Delete":
.. delete record
break;
case "Cancel":
.. cancel record changes and return to previous condition
break;
}
if($submit) {
show form
} else {
show list
}
where list is a display of the records in the database (browse) and the form is a one
record dataentry/modification/delete form.

Re: [PHP-DB] How do you define table row indexes?
In article [EMAIL PROTECTED],
[EMAIL PROTECTED] ("Anyangwe, Tanwani") wrote:
$result = mysql_query("SELECT * FROM motor_vehicle",$db);
$strSep = 'nbsp;|nbsp;';
while ($myrow = mysql_fetch_array($result))

}
Gives me the following error:
Warning: Undefined index: id in C:\PHP\Test_Scripts\testdb2.php on line 16
1) It's not considered a good habit to use "select *" in scripts. When you
later modify the table defs, your scripts will be blown. Even if you never
add/drop/change a column, it's still messy since whenever you're working on
the code you have to remember--accurately--all of the columns and exactly
(case_sensitive_ what they are named. Yuck. Much cleaner to include the
column names in your query now. "Select id from motor_vehicle"--then you
know for sure you're working with a column of that name.
2) mysql_fetch_array doesn't fetch NULLs. If the value of column 'id' in a
given row is NULL, then $myrow['id'] will be undefined for that row. See
http://php.net/manual/en/function.mysql-fetch-array.php.

RE: [PHP-DB] Hold that insert!

Thanks. ;p
My code tends toward:
switch($submit) {
case: "Accept":
.. insert record
break;
case: "Delete":
.. delete record
break;

Just as before, but doing different things depending on
function. That way, the code is still only run when the
form submits. And still, if there are any errors, the same
code is run to (re)display the form. And since all the POST
vars are passed through, the form elements poplulate them
selves with the data that the user previously entered so
the user loses nothing.
I rarely display results on the same page. This allows
me to keep it a little more modular and if I ever need to
modify one, I don't have to worry about touching the
other.
Just out of principle, I like to keep as few ELSEs on a
page as possible. Generally, if you look at the code,
you can streamline things alot just by getting rid of
some of the ELSE statements.

if they exist and if they don't then it will display a blank image...

$img2 = "episodeID_b.jpg";
$img3 = "episodeID_c.jpg";
for ($x=1; $x = 3; $x++) {
