Passing a form variable to a template

[TerryMason]

Lynne,
Thank you very much for helping, but I'm afraid that's over my head. I'm not actually using the variable name variable, but instead it's "player". I' tried this:

<img src="http://www.xxxxxxxx.com/sig/test/1/$_POST['player'].jpg">

but I get this error from my template when I go to save

Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/xxxxxx/public_html/includes/adminfunctions_template.php(3938) : eval()'d code on line 19

Is there anywhere I can go to read about passing variables, or just programming with php inside of VB? Everything I read wants me to use plugins, but I don't think that I can do that with what I'm attempting.

Basically, I just want page1 to have a text input field that the user types into which will forward them to page2 take will that input, and put it in the url of an image file (i.e. www.xxxxxx.com/image/USERINPUT.jpg
