Insert multiple rows into mysql (items separated by comma)

Question

I have a small problem :) I was searching the web but didn\'t find any solutions.

I have a value like this (got it from $_GET[])

tag1, tag2, tag3, tag4

Answer 1

I would convert your comma-delimited tags into an array, then loop through the array to do your inserts.

$data_array=explode(",",$tag); // converts tags to an array based on the comma

// loop through each item in the array
foreach($data_array as $one_tag){

// Get rid of the space you have in your tag string
$one_tag=trim($one_tag);

// Do whatever sanitization you need to do to your data, for example...
$one_tag=mysql_real_escape_string($one_tag);

// Insert into the database
mysql_query("INSERT INTO table SET tag='$one_tag'");

}

You can make this more efficient using Prepared Statements, but it kept this example simple.
