Re: [PHP-DB] Removing first word from a string?
Chris,
I'll try to explain the basics of a technique I often use:
imagine you have 0 or more possible where clauses. start of with an
empty array e.g.
$whereClauses = array();
now for each clause you need add the relevant subclause as a seperate
item to the array (DO NOT include the AND or WHERE string). e.g.
if ($foo) {
// it up to you to make sure $foo is okay for adding to a query string
$whereClauses[] = foofield='$foo';
}
once you have gone thru all the possible subclauses that could exist do
something like this (I'll assume $sql contains the base query):
if (count($whereClauses)) {
// we have a where statement to make
$sql = $sql . ' WHERE ' . join(' AND ', $whereClauses);
}
I leave it up to your imagination how you apply this idea!
greets,
Jochem

one simple trick is to use a clause that always evaluates correctly. For
example, in my site I don't delete data, but flag it with a field
(record_deleted) which defaults to 'No' (actually 0) and can be set to
'Yes' (again 1) so that all queries are built with the requirement to
use AND
ie
$sql = select * from tablename where record_deleted = 0
//code to delevop additional where paramters goes here
if (!empty($_POST['city'])){
$sql .= AND city like '{$_POST['city']}%' ;
}//end if
you could also use the same mechanism that PHPMYAdmin does which is to 1
select * from tablename where 1
since one always evaluates to true and does not affect the query, its a
simple way of doing the same as above

Hi there everyone,
I am building a dynamic MySQL query for a project I am working on, but
there
are instances where it products WHERE AND instead of WHERE city etc
.. due
to the nature of the system I am developing. My question is, how can I
remove the FIRST AND from a string if it is present, but leave all
other
AND statements in the string?
I would really appreciate any help on this. I can do a find and
replace on
a string no problem, but just want it to be removed IF it is the FIRST
word
in the string.
Oh and Happy New Year everyone.
Chris

Re: [PHP-DB] Display records on form
first of all , let me apologize for the top post, second let me apologize for
not giving more detail. The main problem is basically pagination , i have
failed to add pagination code to my own code simply because it is not as
simple as i thought. Considering i am a begginer in PHP , i must give myself
some credit for reaching where i am , as for code snippet here goes,
[snip]
html
titleIP Addresses/title
body
?php
// Get the search variable from URL
$var = @$_GET['q'] ;
$trimmed = trim($var); //trim whitespace from the stored variable
// check for an empty string and display a message.
if ($trimmed == )
{
echo pPlease enter a search.../p;
exit;
}
// check for a search parameter
if (!isset($var))
{
echo pWe dont seem to have a search parameter!/p;
exit;
}
$link = mysql_connect(localhost, me,me2);
mysql_select_db(ip, $link);
$qry = mysql_query(SELECT * FROM IP_Addresses where free like '%.
$_GET['q'].%', $link);
?
table border=1 width=100%tr?php
if (mysql_num_rows($qry)==0 ) {
print Oops No records found ;
?
br
a href=http://localhost/ipsearch2.html;Back/a
/br
?
exit();
}
if (mysql_num_rows($qry) 0) {
for ($i = 0; $imysql_num_fields($qry); $i++) {
echo td align=centerstrong . mysql_field_name($qry, $i) .
/td;
}
}
?
/tr?php
if (mysql_num_rows($qry) 0) {
for ($j = 0; $jmysql_num_rows($qry); $j++) {
?tr?php
for ($k = 0; $kmysql_num_fields($qry); $k++) {
echo td align=center . mysql_result($qry,$j, $k) . /td;
}
?/tr?php
}
}
?
/table
br
br
a href=http://localhost/index.html;Main Page/a
br
br
a href=http://localhost/ipsearch2.html;IP Address Search/a/br/br
/br
/br
/body
/html
[/snip]
i had posted some time back that i have problems with pagination and got alot
of help , but the problem is i have never known how to put the code together
with what i have .. any help is appreciated...
cheers

[PHP-DB] MySQL version issue
As some of you will recall, I enquired on this list about versions of MySQL and PHP a while back regarding and issue wit using the 'ON DUPLICATE KEY UPDATE' command in MySQL INSERT queries. Having upgraded our in-house system to PHP5 and MySQL 4 the issue was no longer a problem. However I have subsequently enquired with our out-of-house web host and they are still using PHP 4.1.2 and MySQL 3.25.58. As one of the purposes of asking them was to establish if I could easily upload from my database to the remote database, I now have a problem. I was planning to use a compare and update script that used 'ON DUPLICATE KEY UPDATE' command in MySQL INSERT queries to add or change items on the remote server. However I can't, as it's a MySQL4 feature and the database to which I am writing ain't using MySQL4!

RE: [PHP-DB] MySQL version issue
Hi Mark, I guess the best way would be to use some php and sql and let the application do the checking. First run a query to acertain if the key is present, if yes then update the main record else insert a new record. bascially you just need to bring the SQL logic into the app logic.

Re: [PHP-DB] MySQL version issue
It seems to me that the _mysql manual_ gives a most straightforward and useful explanation: If you specify the ON DUPLICATE KEY UPDATE clause (new in MySQL 4.1.0), and a row is inserted that would cause a duplicate value in a UNIQUE index or PRIMARY KEY, an UPDATE of the old row is performed. For example, if column a is declared as UNIQUE and already contains the value 1, the following two statements have identical effect: mysql INSERT INTO table (a,b,c) VALUES (1,2,3) ON DUPLICATE KEY UPDATE c=c+1; mysql UPDATE table SET c=c+1 WHERE a=1; The rows-affected value is 1 if the row is inserted as a new record and 2 if an existing record is updated. Note: If column b is unique too, the INSERT would be equivalent to this UPDATE statement instead: mysql UPDATE table SET c=c+1 WHERE a=1 OR b=2 LIMIT 1; If a=1 OR b=2 matches several rows, only one row is updated! In general, you should try to avoid using the ON DUPLICATE KEY clause on tables with multiple UNIQUE keys. Or, you might find a more interesting answer on a MySQL list.
