disable a href links using PHP

Question

I have a page with a menu on for logged in users

i am including this page on all the other pages in my site but i don't want users that are NOT logged in to be able to click the links

How can I disable all the links on that page if a PHP variable = 'no'

i know i can use

if($php_var == 'no') {
    //do something here
}

but I'm not sure how to disable the links?

Is there any way using CSS or Javascript to disable links?

Answer 1

If i understood everything correctly, the answer is quite simple. Why dont you just replace the links with plain strings?

if($php_var === "no") {
    echo "This is the text of your link.";
} else
{
    echo "<a href="your.link">This is the text of your link.</a>";
}

But as already mentioned, completely hiding the links is better, as usual users gets confused by such things.

Answer 2

this will remove all href from a tags. If php var is no. Put this code after all a tags else won't work

 <?php
    if($php_var === "no"){
    echo '<script>var x=document.getElementsByTagName("a");for (i=0;i<x.length;i++){x[i].removeAttribute("href");}</script>';
    }

?>

You would need to do the processing pre-output, PHP will not dynamically disable the href of an already created DOM element.

If you are producing the output of the links via PHP, you could do something like:

echo '<a href="' . ($php_var == 'no' ? '#' : 'actual_link.html') . '">Link</a>';

Otherwise, you could create an AJAX call to the PHP script, and if it returns 'no', iterate through your pages links and disable the links via JavaScript.

Answer 4

try this

if($php_var == "no")
{
    echo '<a href="javascript:void(0);">Your Text For Link</a>';
} 
else
{
    echo '<a href="your link">Your Text For Link</a>';
}

user javascript:void(0); for no redirection. this will maintain your css for link like others but when you click it won't redirect.
