Help with undefined variable error

[ChrisJ]

I am trying to display some text "THIS IS A TEST" on the html page.

I am getting this error:

"Notice: Undefined variable: text1 in /home/public_html/themes/videos/content.html on line 23"

Here is the php file ( I added line 35 and 39):

<?php

declare( strict_types=1);
// these should be set in PHP.ini
error_reporting(-1); // set maximum errors
ini_set('display_errors' , 'true');

if (empty($_GET['page'])) {
    header("Location: " . PT_Link('404'));
    exit();
}
$page         = PT_Secure($_GET['page']);
$limit        = 20;
$pt->rss_feed = false;
$pt->exp_feed = true;
$pages        = array(
    'trending',
    'category',
    'latest',
    'top'
);

if (!in_array($page, $pages)) {
    header("Location: " . PT_Link('404'));
    exit();
}

if (!empty($_GET['feed']) && $_GET['feed'] == 'rss') {
    $limit        = 50;
    $pt->rss_feed = true;

}

$text1 = 'THIS IS A TEST';
$cateogry_id = '';
$videos = array();

$text1 = 'trending';
    $title  = $lang->trending;
    $db->where('privacy', 0);
    $videos = $db->where('time', time() - 172800, '>')->orderBy('views', 'DESC')->get(T_VIDEOS, $limit);
}

    $title  = $lang->latest_videos;
    $db->where('privacy', 0);
    $videos = $db->orderBy('id', 'DESC')->get(T_VIDEOS, $limit);
}

    $title  = $lang->top_videos;
    $db->where('privacy', 0);
    $videos = $db->orderBy('views', 'DESC')->get(T_VIDEOS, $limit);

Any additional guidance to remedy this error is appreciated.

It would be most helpful if you can help us isolate the error. Some of the tools that can help are PHP function var_dump(), and a current list of the documents without any qualifications. For example, your post says, "I added line 23" and since the post says "Undefined variable: text1 ... on line 23" we would naturally look to line 23 for the first step of the debugging process -- but neither line 23 has any reference to $text1, so we're kind of stuck. Without accurate line numbers and a faithful representation of the exact code set, there is not much chance that you can get a good answer from the community!

A good concept for questions like this is the SSCCE (google it). Then please put together an example that follows the SSCCE guidelines. Once you do that we are almost certain to be able to help!

From what I can see, the php file creates the variable $text1 and the html file references the variable $text1, but the html file doesn’t include the php file which has to be done with php.
