<input type="text" id="url" value="https://www.example.com<?php echo $_SERVER['REQUEST_URI']; ?>" style="width:600px;height:30px;font-size:25px">

How can i submit this input when page loads??

And the only way i can submit this input is by pressing ENTER Key.

i tried to do a button submit but it didn't work.

I am doing this because for example i enter the www.example.com/BillGates and when i enter this page url i use a php code to get the current page url so i put it in the input value, when i open the page i don't want people than to press the enter key in the input form but i want the get the results automatically on page load so they don't need to press the enter key.

Answer 1

well you can do this.............

 $(document).ready(function(){

      $("#enter_key_id").click();

 });

this click your enter button at page loads................

Answer 2

You can't submit a input but you can submit a form:

In your PHP:

<form id="form-id" action="url.php" method="POST">
  /* better hidden than text if you don't want to the user can change it */
  <input type="hidden" name="url" value="http://www.example.com...<?php print $anything; ?>" />
</form>

In your JS:

$(document).ready(function() {
  $('#form-id').submit();
});

But i don't understand why you need to do this. It's no better to do a curl call from the first PHP?
