如何在单引号之间添加两个变量

Question

I have

function delImage(posteId,imagebinId) { 
    $.get("<?php  echo base_url('/Home/deletePostimage/') ?>"); 

    return false; 
} 

i want to be like /Home/deletePostimage/posteId/imagebinId

i tried

$.get("<?php  echo base_url('/Home/deletePostimage/')+posteId+"/"+imagebinId ?>"); 

but it divide the two numbers

like posteId=5 imagebinId =2

the results will be

/Home/deletePostimage/2,5

the params from

<a class="postimgsd" onClick="if(confirm('Are you sure you want to delete this image ?')){delImage(<?php echo $value['id'],$get_images[0]['binId']; ?>); rmItem(<?php echo $i; ?>);}else{} ;  " >

Answer 1

With ES6, you can do this with string interpolation :

$.get(`<?php  echo base_url('/Home/deletePostimage/${postId}/${imagebinId}') ?>`);

Without ES6, there is another answer that answers it, or use this:

var url = '/Home/deletePostimage/' + postId + '/' + imagebinId;
$.get("<?php  echo base_url('" + url + "') ?>");

Furthermore, the code that calls this function should actually be:

<a class="postimgsd" onClick="checkDeletion()" />

<script type='text/javascript'>
    function checkDeletion() {
        if(confirm('Are you sure you want to delete this image ?')) {
            var postId = <?php echo $value['id']; ?>;
            var imagebinId = <?php echo $get_images[0]['binId']; ?>;
            delImage(postId, imagebinId);
            rmItem(<?php echo $i; ?>);
        }
    }
</script>

You need to keep in mind that PHP is processed on back-end before send the html to your user browser. That said, everything between php tags ( <?php ... ?> ) is rendered/processed before javascript even exists.

So if you put any JavaScript code inside your PHP code it won't work.

To make it work and be clean, do something like this:

function delImage(posteId,imagebinId) { 
    let url = "<?php  echo base_url('/Home/deletePostimage/') ?>";
    $.get(url + posteId + "," + imagebinId); 

    return false; 
}
