Scenario: I've a link to download a pdf file. Upon clicking it, an ajax call runs and returns the file to download. (Ajax implemented to hide the file path for security reasons)
Problem: The code is working perfect with http/non-ssl path. But when site is moved to https the same code is not working.
Question: Is there any thing which i am missing for SSL/HTTPS into the code? This code is written in to wordpress
<a class="red contract-btn" id="contract_link" data-contract="<?php echo base64_encode($cont_file); ?>" href="" >View Contract</a>
<script>
jQuery("#contract_link").on('click',function(e){
e.preventDefault();
var $this=jQuery(this).data('contract');
var ajaxData = {
'action': 'contract_file_download',
'cont_file':$this
}
jQuery.ajax({
type: "POST",
url: "<?php echo admin_url('admin-ajax.php'); ?>",
data: ajaxData,
success: function( response ) { },
error: function() {
alert("Error!");
}
});
});
</script>
PHP:
add_action("wp_ajax_contract_file_download", "contract_file_download");
add_action("wp_ajax_nopriv_contract_file_download", "contract_file_download");
function contract_file_download(){
$File_path=base64_decode($_POST['cont_file']);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="' . basename($File_path) . '"');
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . filesize($File_path));
ob_end_flush();
set_time_limit(0);
readfile($File_path);
}
I believe ...I am maybe wrong ... You are maybe not changed all urls inside WordPress properly.
If you did, according to https://codex.wordpress.org/Function_Reference/admin_url
admin_url('admin-ajax.php','https');
use second parameter to force https
