Do not pull information on index only

Question

Well I’ll try to explain it as best I can, I know it can be simple but at the same time I don’t know how I can do it...

Let’s say in my Header I have a 'bar' that I would like to appear on all pages that I pull the MINUS header into the index because of a Slide that I put...

(in case that blue bar I wanted it to appear on all pages except in index)

Solution if it is a div in itself.

    <?php
var_export($_SERVER['REQUEST_URI']);
$array = explode("/", $_SERVER['REQUEST_URI']);
$url = str_replace("/", "", $_SERVER['REQUEST_URI']);
$pagina = end($array);


if ($url != 'apcefsp') {
    ?>
    <div><img src="http://localhost/apcefsp/wp-content/uploads/2017/10/ficha-1.png" alt="" width="100%" height="5"/></div> 
    <?php
}
?>

Is there any way to pull the different header ? or any CSS that makes such a div not appear except in index ?

Answer 1

This way you take the current page, if it is different from 'index.php' it includes the code with the bar.

<?php
$array = explode("/", $_SERVER['PHP_SELF']);
$pagina = end($array);
if($pagina != 'index.php'){
    include 'barra.php';
}

For DOM element as a div:

<?php
$array = explode("/", $_SERVER['PHP_SELF']);
$pagina = end($array);
if ($pagina != 'index.php') {
    ?>
    <div>Sua div</div>
    <?php
}
?>

Explaining the code

Takes the current url without the host:

$_SERVER['PHP_SELF']

Example:

/page/test.php

Create an array with the division of the string that are separated by "/":

var_export(explode("/", $_SERVER['PHP_SELF']));

Example:

array ( 0 => '', 1 => 'pagina', 2 => 'teste.php', )

Takes the last array item:

$pagina = end($array);

In the case of this example:

'php test.'

Then it checks if it is not on the index to show the div:

if ($pagina != 'index.php') {
    ?>
    <div>Sua div</div>
    <?php
}

To solve the problem it was necessary to use $_SERVER['REQUEST_URI'], since the variable was dynamic, but the idea is the same as in the above example.
