Show and Hide Button (href=) if file exist in server or not
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I tried editing a similar solution but it doesnt do what it was intended to. Im not sure about my coding maybe im wrong and im using html. Is there a way to hide button(href=) if file exists then show if its not found? thank you!
ref: link
<button type="button" id="test_btn" style="display: none;">Download</button>
<script type="text/javascript">
$(document).ready(function () {
checkFile();
function checkFile() {
$.ajax({
url: '/path/to/file_checker.php',
type: 'GET',
success: function (data) {
if (data === "deleted") {
$('#test_btn').show();
}
else {
$('#test_btn').hidden();
}
}
});
}
}
</script>
Then your file checker php can be something similar to what you had:
if (file_exists("/aaa/file.txt")) {
echo "exists";
}
else {
echo "deleted";
}
php css display

A different approach would be to offer a list of the files that exist to the user and allow them to select from the list.
<?php
// Initialize an empty array
$files = ;
// Get all the files in a directory (this will also return directories)
foreach (glob('*') as $f) {
// If the item is a file, add it to the files array
if (is_file($f)) {
$files = $f;
}
}
?>
<!-- Create a select statement with the files that exist -->
<select id="files">
<!-- Placeholder -->
<option disabled selected>Select file</option>
<!-- Loop through all the files and create options for them -->
<?php foreach ($files as $f) : ?>
<option><?= $f ?></option>
<?php endforeach ?>
</select>
<!-- The button would run the download using the selected file as the source (additional JavaScript required) -->
<button id="go">Download</button>
wow thats great! i will try and learn how to implement this one. thank you very much!
