I am using php and trying to add a item to my MySQL database.

I am using php and trying to add a item to my MySQL database.

If I use the following code it works:

 mysql_query("INSERT INTO `intranet`.`product_form` (`id`, `ProductName`, `ProductInitiatedBy`) VALUES (NULL,  'item1', 'item2')") or die("Could not perform select query - " . mysql_error());;

However, if I use the following code it doesn’t work:

$product_name=("tom"); 
mysql_query("INSERT INTO `intranet`.`product_form` (`id`, `ProductName`, `ProductInitiatedBy`) VALUES (NULL,  $product_name, 'item2')") or die("Could not perform select query - " . mysql_error());;

I get an error that says:

Could not perform select query – Unknown column ‘ProductName1234’ in
‘field list’

The ProductName1234 is the data from $product_name and should be the data I am trying to add and not the column.

    Change:

    mysql_query("INSERT INTO `intranet`.`product_form` (`id`, `ProductName`, `ProductInitiatedBy`) VALUES (NULL,  $product_name, 'item2')") or die("Could not perform select query - " . mysql_error());;

    to:

    mysql_query("INSERT INTO `intranet`.`product_form` (`id`, `ProductName`, `ProductInitiatedBy`) VALUES (NULL,  '$product_name', 'item2')") or die("Could not perform select query - " . mysql_error());

    You need to add ' to $product_name:

    VALUES (NULL,  '$product_name', 'item2')
