Question

I have this simple form:

<form ENCTYPE="multipart/form-data" action="story.php" method="POST">
<input type="submit" value="Show files">
<input type="hidden" name="emailp" id="emailp" value="">
</form>

I fill the “value” with a querystring parameter by external iframe and javascript.
Ok. Now I need to send this data to a php file.
My idea was go for autosubmit.
Now I can do that with a button like “show files”, but I dont need a button but something that send the value automatically.
Is it possible do that?

Call a this JS code that submits the form after you set the value of the input.

document.getElementById("storyForm").submit();

HTML:

<form ENCTYPE="multipart/form-data" action="story.php" method="POST" id="storyForm">
<input type="submit" value="Show files">
<input type="hidden" name="emailp" id="emailp" value="">
</form>
