Question

I’m new to PHP but I think it’s possible, thought unsure how to achieve this.

I’ve got a basic HTML markup inside a PHP file called button.php which I’m injecting into a web page using PHP include.

Here’s the contents of the button.php file:

<div class="btn">
<div class="highlightBtn">
    <div class="btnTag">
        Submit
    </div>
</div>
</div>

The question is – how do I the value inside the class=”btnTag” tags AFTER I’ve included it? (I.e. after I include this file into the main page I want to be able to change it depending on where it’s included, so it doesn’t always have to say ‘Submit’).

So I imagine it might be something like

<? php include("button.php"); 
   //some code follows to change value inside the btnTag class  
?>

Thanks for your help!

Answer 1

It really should be done beforehand, as in

// button.php
<div class="btn">
<div class="highlightBtn">
    <div class="btnTag">
        <?php echo isset($caption) ? $caption : 'Submit' ; ?>
    </div>
</div>
</div>

And then

<?php
    $caption = 'Click me'; // or comment out to get the default
    include('button.php');
?>

However, the above is not really a good approach

It would be much better to have the file just define a function when included, which you can then call whenever you need a button. For example:

// button.php
<?php
    function button($caption = 'Submit') {
        echo <<<END_HTML;
<div class="btn">
  <div class="highlightBtn">
    <div class="btnTag">$caption</div>
  </div>
</div>
END_HTML;
    }

You can then include button.php without any immediate effects, and whenever you want a button you can just call button('Click me') or just button().
