Need help with using a button/link to autoinsert text into a field on opening

What I want to do is use a graphic that is linked to page that ends in .php

This page has a form. In one of the fields of the form I want it to enter text based on the code that I used in the button.

I also did not design the page with the form and cannot do anything on it. I want it to be changable for different people. I also can’t use javascript.

Here is the code for the field I want to insert the text into…

<input type=“text” name=“NAME_1” value="" style="width:208px; height:27px; font-size:14px; font-weight:bold; padding:3px>

Any direction or help would be much appreciated :slight_smile: Thanks
