How to ‘insert if not exists’ in MySQL?

Written by leif. Posted in Mysql, PHP, Tips

see http://bogdan.org.ua/2007/10/18/mysql-insert-if-not-exists-syntax.html

there’s also INSERT … ON DUPLICATE KEY UPDATE syntax, you can find explanations on dev.mysql.com

To start: as of the latest MySQL, syntax presented in the title is not possible. But there are several very easy ways to accomplish what is expected using existing functionality.

There are 3 possible solutions: using INSERT IGNORE, REPLACE, or INSERT … ON DUPLICATE KEY UPDATE.Imagine we have a table:

CREATE TABLE `transcripts` (

$pdf->Cell(40,5,'[ x ] checkbox1′,1,0,’L’,0);
$pdf->Cell(40,5,'[ x ] checkbox2′,1,0,’L’,0);
$pdf->Cell(40,5,'[ x ] checkbox3′,1,0,’L’,0);


$pdf->Cell(40,5,'[ x ] checkbox4′,1,0,’L’,0);
$pdf->Cell(40,5,'[ x ] checkbox5′,1,0,’L’,0);
$pdf->Cell(40,5,'[ x ] checkbox6′,1,0,’L’,0);

Do not use any of the suggested versions of PHP_SELF. It is a security nightmare, opening up your PHP to a multitude of possible injection attacks.

What are you trying to achieve? Generate the URL for a form sending to itself? Use action=”” for that – it is a valid approach and will always use the URL for sending the form as for loading.

If you must know the requested script, use $_SERVER[‘SCRIPT_NAME’] instead.

Or $_SERVER[‘PHP_SELF’], not $PHP_SELF. See the docs
