How to Remove A File From A File Input In Laravel?

5 minutes read

To remove a file from a file input in Laravel, you can reset the value of the file input by using JavaScript. You can do this by targeting the file input element and setting its value to an empty string. This will effectively remove the file that was previously selected.


Here is an example of how you can accomplish this:

1
document.getElementById('fileInput').value = '';


In this example, 'fileInput' is the id of the file input element that you want to remove the file from. By setting its value to an empty string, you are clearing the selection and effectively removing the file.


Alternatively, you can also use jQuery to achieve the same result:

1
$('#fileInput').val('');


Just like the previous example, this code snippet targets the file input element with the id 'fileInput' and sets its value to an empty string.


By using either of these methods, you can easily remove a file from a file input in Laravel.
