Echo ALT attribute of random image

Question

I have this little script that displays a random image, which is:

<img src="<?php echo bloginfo('template_url');?>/img/members/00<?php $random = rand(1,7); echo $random; ?>.jpg"alt="[ Random Image ]">

This makes the image src src="example.com/images/001.jpg" alt="[ Random Image ]"> the (1,7) in the script adds the number of the image 001.jpg to 007.jpg .

Now what I would like is to change the "[ Random Image ]" in to "$my_alt" and have it display (echo) the alt attribute of the image in a <h2 class="myAlt">...</h2> tag.

I'm not that of a coder, so I don't really know how to do this. I believe I would first need to give my_alt a value. So I would go by:

if {image src="example.com/images/001.jpg" $my_alt = "My first Alt"} else if {image src="example.com/images/002.jpg" $my_alt = "My second Alt"}

and then where I want the value of the alt to be placed add the code: <h2 class="myAlt"><?php echo $my_alt(); ?></h2> <h2 class="myAlt"><?php echo $my_alt(); ?></h2>

Am I doing this correct, is this the right way to go? Like I said I'm not that good at coding, so thanks for the help.

Answer 1

I got your problem. Try this to see if it works:

<!-- I am gonna make a sample template so that you may understand how to use my solution for your specific issue -->
 <div class="imageContainer">
    <img src="something" alt="Image1" />
    <h2 class="myAlt"></h2>
</div>
<div class="imageContainer">
    <img src="something" alt="Image2" />
    <h2 class="myAlt"></h2>
</div>
<div class="imageContainer">
    <img src="something" alt="Image3" />
    <h2 class="myAlt"></h2>
</div>
<div class="imageContainer">
    <img src="something" alt="Image4" />
    <h2 class="myAlt"></h2>
</div>

<script>
$('.imageContainer').each(function(){
    $(this).find('.myAlt').html($(this).find('img').attr('alt'));
});
</script>

It will show the respective alt below every image.

for particular two images

// giving alt dynimically
    $('img').each(function(){
        if($(this).attr('src')==='image 001.jpg'){
            $(this).attr('alt','person x');
        }
        else if($(this).attr('src')==='image 002.jpg'){
            $(this).attr('alt','person y');
        }
    });

its just an idea, you need to modify it to suit your particular problem. Good luck. I hope it helps

I would create an array with all images and their alt s, then choose one of them and display it:

<?php
$images = [
  ['file' => '001.jpg', 'alt' => 'My first alt'],
  ['file' => '002.jpg', 'alt' => 'My second alt'],
  ['file' => '003.jpg', 'alt' => 'My third alt'],
  # add more files below
];
$rand = mt_rand(0, count($images) - 1);
?><img src="<?php echo bloginfo('template_url');?>/img/members/<?php echo $images[$rand]['file']; ?>" alt="<?php echo $images[$rand]['alt']; ?>">
