Dynamic Post Variables

Recommended Posts

On my html form, I'm creating dynamic textboxes with javascript whenever the user selects an "Add New" button.  However, when I post the page back to the server I am having problems deciding how to best parse the dynamic fields because I am unsure how many fields were created or if others that were previously created are now deleted.  For example, when the data is posted back, I could have the textboxes "textbox1, textbox2, textbox3" or I could have "textbox3, textbox5, textbox6" if the user added fields and then deleted some of them.  If anyone could help point me in the right direction, I would appreciate it.  Also, if more information is needed, please let me know.  Thanks.

Use an array, either specifically numbered textbox[1], textbox[2]... or let them be numbered by the browser textbox[], textbox[]...

 

Then in the form processing code you can simply use a foreach() loop to iterate over them -

 

foreach($_POST[textbox] as $value)
{
   echo $value;
}
