[PHP-DB] Re: Dynamic Drop Down Box
So, if the user selects "mercedes", then the next box is "500Sl, 300Sc" and so forth. If they select ford, then the second box has completely different values? You'll either have to reload the page after the first select, or use javascript or some other kind of client script. I don't think there is a way to do it with PHP, but maybe someone else has an idea to help you. I hope they do, because I need to do the same sort of thing, and I am trying to avoid js at all costs.

[PHP-DB] Re: multiple select statements
There are even easier ways to do it than that... using if statements. so,
start with something like this:
$query.="select ";
then let's say you have a buch of clickboxes which your user can check which
will construct your select statements, so,
if ($clickbox1="") {
$query.="";
}
if ($clickbox2="") {
$query.="";
}
then at the end: $query.="from ";
mysql_query($query)... and off you go...don't forget the little period,
otherwise it won't concat everything together as you build your query. If
you need to select from different tables, just add another variable to your
if statements..
If you want to see a real example, here's a snip I use to built an insert
statement, which will take any number of values from an array, create a
table based on their field names, and then insert them into that table..:
//start of insert...
$insert.="insert out_fuzzy set ";
$count=$count+1;
//loops through array
for ($i=0; $i<$cols_compare; $i++)
{
$insert.=mysql_field_name($result_compare, $i);
$insert.="_compare=\"";
$insert.=$compare[$i];
$insert.="\", ";
$insert.=mysql_field_name($result_compare, $i);
$insert.="_base=\"";
$insert.=$result_base[$i];
$insert.="\", ";
$insert.=mysql_field_name($result_compare, $i);
$insert.="_pct=\"";
$base_tmp=trim(strtoupper($result_base[$i]));
$compare_tmp=trim(strtoupper($compare[$i]));
$number=similar_text($base_tmp, $compare_tmp, $last_sim);
$insert.=number_format($last_sim,1);
$insert.="\", ";
Hope that helps.

Re: [PHP-DB] Tutorial?
Right. I store mine in the same db, and it gets inserted with the other data
from the form. Before inserting, the script does a quick query, selecting
all rows where the unique_id is equal to the current ID. since a new one is
generated for each submit click, the answer will be zero on a proper insert.
On a reload, the answer (mysql_affected_rows) will be 1, so you exit the
script at that point. I also check to make sure the required fields are not
blank before inserting, so that handles the problem of inserting a blank
record if the user clicks twice.
anyway, it works... you can click and click and click all you want, reload
until you're blue in the face, and you'll only get one proper insert. better
yet, not a word of javascript was involved. :)

The easiest and best solution is to redirect to a new page after the submit. But I have had cases where it was necessary to have the submit code and the form on the same page. I agree totally with jonathan that a server-side solution is the way to go. To solve the problem (avoid clicking twice and/or reloading the page) I used a hidden field that generated a unique ID based, and then placed that into a field that only accepts unique values.

Re: [PHP-DB] Tutorial?
Could you not put the form inside an if/else statement? If the button isset, or if the name equals submit, then show it disabled. Can't think of a lot of uses for this, unless, I suppose, you want to have a page with lots of forms on it, and you want to submit pieces of information. It wouldn't prevent users from reloading the page and creating duplicate records.

[PHP-DB] Anyone with suggestions to make this run faster?
hey folks, I just got done writing a function to help with my data cleaning. It works - actually a lot better than I thought it would - but I am sure there are ways I could optimize this somewhat. The function takes two result sets (usually first name, last name, city, state, zip) from two tables, then calculates the similar_text() value for each pair (first name from table one, versus first name from table two, and so forth) and places those values into a new table. What I end up with is a sort of fuzzy matching lookup table, so I could look up all values where there is a 90 percent match in each category (for example), and then use that to update my original tables. Hope that makes sense. Anyway, here's the code. If anyone has any suggestions (such as, is it faster to dump into a local file and then move that into a table?), I'm all ears.

[PHP-DB] Re: PHP Question on MySQL grouping
depending on how you print the result set to the browser, you just need to add an echo "" at the end of each line. So, if you've fed your result set into an array called $row, then something like: print "$row[0] . $row[1] . $row[2] . ""; That should print out each result followed by a horizontal rule.

[PHP-DB] Re: I'm really stuck!
First, could you be more specific? What isn't working? What error messages
are you getting? (I assume you are echoing them, because if not, you should
be... mysql_query($query) or die (mysql_error());
Second, this could be a problem. I think you need single quotes around the
variable here:
$query = "select bin_data, filetype from image_data where
id=---'$id'"; -
Beyond that, I can't really help much. Never stored image data in a db
before, so I can't tell you if anything else might be amiss. Good luck.

Hi all,
I'm really stuck and I'm not asking anyone to re-write this just show me
what is wrong, or explain why it wont work. It just seems logical that this
should work.
The first query will print the pet id in the browser.
$query="SELECT id FROM wt_users WHERE uid={$session["uid"]}";
$ret = mysql_query($query);
while(list($pet)=
mysql_fetch_row($ret))
print("your pet id is $pet");
So if $pet will print the id from the wt_users (has a value of 3) and I
assign $id = $pet (id also has a value of 3 in image_data) why doesn't it
show the image?
if($id) {
$id = $pet;
$query = "select bin_data,filetype from image_data where id=$id";
$result = mysql_query($query);
$data = mysql_query($result,0,"bin_data");
$type = mysql_query($result,0,"filetype");
Header( "Content-type: $type");
echo $data;
};
echo "";

do you mean uid in wt_users? So, $id=session ID? I might set that ahead of
time just to make it simpler.
Therefore, you really only need one select statement. I'm no expert at this,
and you may need to tweak this a little, but this should work :
select ., . from wt_users,
image_data where $id=wt_users.uid and $id=image_data.id
substitute the table name and field names for .,
obviously. For example, wt_users.uid, image_data.id and so forth. That
should get you on your way.

[PHP-DB] Looping through two arrays
This one seems like it should be easy, but I can't get anything to work. I
have two tables. I want to pull a first name and last name from each table,
a master table and a new table. Then, I want to list them in a specific way:
I want to list the first name of the master table, then list all the names
from the new table, then i want to move to the second name in the master
table, and list all the names in the new table again, and so forth until I
have listed all combinations.
I have been able to list the first name from the master table, and all the
names from the new table, but the loop stops right there. It won't go to the
second name in the master and relist all the names from the new table. I
suspect I need a "foreach" instead of a "while," but I am just learning the
importance of arrays so I am not real good with the syntax as yet.
Any help is greatly appreciated. Here's the code:
while ($row_new = mysql_fetch_row($res_master))
{
while ($row_old = mysql_fetch_row($res_new))
{
echo($row_new[0] . $row_new[1]);
echo($row_old[0] . $row_old[1] . "");
}
}

[PHP-DB] Re: Sorting the result
Not sure I totally understand the question, but I think the answer is no
because your count isn't part of the database, nor is it part of the query.
You're asking MySQL to sort a field that doesn't exist, in other words.
The only way around that is to have MySQL calculate the number of occurances
as part of the actualy SQL statement, and off the top of my head I can't
think of a way to do that. There is not a function (I know of) that works
like substr_count() in SQL.
Maybe someone else has a better answer for you, but that's the best I can
do. sorry!

[PHP-DB] Re: MySQL problem
It means there is a problem with your query. I'm not familiar with the
die(1) and die (2) syntax. I'm not sure what that does, but you might try
echoing your error message from the query to see what message you get.
Hope that helps.

[PHP-DB] PHP IDE
After spending two frustrating hours tracking down a bug yesterday - only to discover it was a misplaced quote mark. I've had it. I am looking for suggestions out there for a good IDE for PHP development, preferably one that doesn't cost an arm and a leg. I tried PHP4EE studio, but it is buggy as hell and kept crashing on me.
