To create a file upload form, you must use the "file" field within a form with the enctype attribute set to 'multipart/form-data'.
inputEx({
type: 'form',
parentEl: 'container1',
enctype: 'multipart/form-data',
action: 'input_file.php',
fields: [
{type: 'file', name: 'textFile', label:'Search file', accept: 'text/*', size: 50 }
],
buttons: [
{type: 'submit', value: 'Upload'}
]
});
