The example in this article describes a workaround for CodeIgniter shopping cart classes that cannot be added in Chinese. Share to everyone for your reference. The specific analysis is as follows:
A friend may find that CodeIgniter shopping cart class can not add Chinese, I found a long time to find the following code to limit the input of Chinese, modify systemlibrariescart.php, comment 第186-190 line product name judgment, the code is as follows:
Copy Code code as follows:
if (! Preg_match ("/^[". $this->product_name_rules. "] +$/i ", $items [' name '])
{
Log_message (' Error ', ' an invalid name is submitted as the product name: '. $items [' name ']. ' The name can only contain alpha-numeric characters, dashes, underscores, colons, and spaces ');
return FALSE;
}
However, delete is not the best way, we can directly change the regular match to Chinese on the line. Interested friends can refer to this "PHP regular expression verification of Chinese problems."
I hope this article will be helpful to everyone's thinkphp framework program design.
