I found the article in the knowledge base about adding PHP. I downloaded the Simple PHP plugin, and added
echo “This is our custom template!”;
I tried it with and without a closing ?>
This is what I get now:
This is our custom template!
Warning: Cannot modify header information – headers already sent by (output started at /home/bsa566/public_html/wp-content/plugins/generate-simple-php/custom.php:8) in /home/bsa566/public_html/wp-content/plugins/wpclef/includes/lib/wp-session/class-wp-session.php on line 130Warning: Cannot modify header information – headers already sent by (output started at /home/bsa566/public_html/wp-content/plugins/generate-simple-php/custom.php:8) in /home/bsa566/public_html/wp-content/plugins/custom-database-tables/lib/webapis.php on line 131

Also, I am a little confused. I want to write some custom PHP (custom database table access) on just a subset of the pages, not all of them — is this the right way to do it?
July 10, 2016 at 2:28 pm #208038TomLead DeveloperLead DeveloperCan you paste the entire contents of your simple PHP code into a pastebin and show me?: http://pastebin.com/
Looks like there might be an error in there.
July 11, 2016 at 5:13 pm #208548Nik BhattI have pasted it to <http://pastebin.com/Fd0ESh8M>
July 11, 2016 at 7:49 pm #208574TomLead DeveloperLead DeveloperNot seeing anything wrong with it, but it just might be that you’re echoing code which can interfere with other code.
Try this instead:
add_action( 'generate_before_header','generate_test_function' ); function generate_test_function() { echo 'This is a test.'; }
July 11, 2016 at 11:09 pm #208590Nik BhattOK – I tried that and I don’t get any errors now. Thanks!
However, if I call that method (generate_test_function()) I get the same problem. It looks like it’s because the script code is injected PRIOR to the <html> tag (see below). That seems bad, but not fatal. Assuming it’s okay, this brings up my other question. I can define functions here, but how do I call them (and only on some pages, not all of them)? Calling them in the simple PHP causes an error. In my use case, I want to provide a search UI against some custom database tables, but only for certain pages, not all.
Thanks.

<script type=”text/javascript”>July 11, 2016 at 11:29 pm #208592TomLead DeveloperLead DeveloperCalling a function directly in that file will cause errors, as that file is for defining functions, or hooking them into the template.
If you define a function in there, you need to then call that function inside a template file, inside a function which hooks it into the template (my example), or in GP Hooks.
Hope this helps ๐
July 27, 2016 at 6:08 pm #213426Nik BhattA few questions. The answer may be the same for both ๐
1) I find that some of my HTML that I put into PHP is being ignored when in Generate Press pages. For example, table borders are always present, the align attribute is ignored, as is colspan for a TD. They work fine if I just make plain HTML and open it in the same browser. How can I get those to work again?
2) I have an IFRAME that runs some PHP code. Though I’ve turned off all the page attributes, like footer, sidebar, etc., I still get a thick gray background color at the bottom and the page contents are inset. Is there a way to have GP just show a page without any “GP stuff”? I need access to WordPress database calls so it can’t be a vanilla PHP somewhere random.
July 27, 2016 at 11:37 pm #213468TomLead DeveloperLead DeveloperHi there,
1. This will remove the borders: https://generatepress.com/forums/topic/table-boarders/#post-129050
The align attribute should be replaced with CSS.
You can remove all of GP’s styling of borders with this CSS:
table { border-collapse: initial; border-spacing: initial; border-width: initial; } table, td, th { border: initial; }
2. Can you link me to the page so I can see?
