aseaofflames Posted June 7, 2008 Share Posted June 7, 2008 you can't directly call a javascript function from php. however you could use php to create a body onload event to run the script. example: if (!$_POST['site_name'] || !$_POST['site_url'] || !$_POST['administration_username'] || !$_POST['administration_password'] || !$_POST['mysql_server_name'] || !$_POST['mysql_username'] || !$_POST['mysql_password'] || !$_POST['mysql_database_name'] || !$_POST['mysql_table_prefix']) { echo "<body onload=\"incomplete_field()\">"; //tells the browser to run incomplete_field() when the page loads } else { $mysql_connect = mysql_connect("$mysql_server_name", "$mysql_username", "$mysql_password") or die(mysql_error()); } i changed your | to || (the correct or in php) Link to comment https://forums.phpfreaks.com/topic/109115-php-if-statement-with-javascript/#findComment-559830 Share on other sites More sharing options...
DarkWater Posted June 7, 2008 Share Posted June 7, 2008 i changed your | to || (the correct or in php) That's not the correct OR, that's the logical OR. The other one that he had is a bitwise OR. Although you'd be correct in saying that a majority of the time you'd use || or &&, you don't when you actually need to work with bitwise operators. EX: if (imagetypes() & IMG_PNG) { echo "PNG enabled". } Link to comment https://forums.phpfreaks.com/topic/109115-php-if-statement-with-javascript/#findComment-559846 Share on other sites More sharing options...
