Javascript autosubmit form - php

I have a form that I need to submit automatically... (the fields are already filled and its complicated to explain why but it IS necessary to do it this way)..
I know how to autosubmit the form using Javascript but the only problem I have is that there is more than 1 submit button.. and I need 1 in particular to be submitted...
thanks in advance
EDIT2(source):
<I put the javascript in the head... />
<FORM ACTION="PDF.php" name="form" METHOD="post">
<A whole bunch of inputs />
<INPUT TYPE="submit" name="form-save" VALUE="Save Changes" >
<INPUT TYPE="submit" name="form-submit" VALUE="Submit" >
<input type="submit" name="print" id="print" value="Download PDF" />
</form>

instead of going for a click event on a submit button, you can call submit of a form object from javascript.
Example :
<head>
<title>Auto Submit Form</title>
<script type="text/javascript">
window.onload = function () {
var form = document.getElementById("PDFGenerationForm");
form.submit();
};
function OnFormSubmit() {
alert("Submitting form.");
}
</script>
<body>
<form id="PDFGenerationForm" action="" method="post" onsubmit="OnFormSubmit">
<!--Any input tags go in here-->
</form>
This editor won't let me paste the whole HTML in here. So, it is in fragments.

$("#yourbuttonid").click();
EDIT:
<form>
...
<input type="submit" id="myFirstsubmit" />
<input type="submit" id="mysubmit" />
</form>
<script type="text/javascript">
$(document).ready(function(){$("#mysubmit").click();});
</script>

If you really want to click a specific button, add this script to the end of your page:
<script type="text/javascript">
// press the button
var myButton = document.getElementById("idOfTheButtonToClick");
myButton.click();
</script>
This assumes your button has an ID.

1) Here is a working auto-submit method: when page is loaded, the form will be immediately autosubmited (the values can be set with php variables too.)
<form action="page.php" name="FORM_NAME" method="post">
<input type="text" name="example1" value="YOUR_VALUE" />
<input type="submit" />
</form>
<SCRIPT TYPE="text/JavaScript">document.forms["FORM_NAME"].submit();</SCRIPT>
or use for any form on that page:
document.forms[0].submit();
2) you can use button-click (called after 1 second):
<SCRIPT TYPE="text/JavaScript">setInterval(function () {document.getElementById("myButtonId").click();}, 1000);</SCRIPT>

You need a client-side script to manage this. I'd recommend something in jQuery.
<script type="text/javascript">
$(document).ready(function(){
$(".myButton").click(triggerPopup);
})
function triggerPopup(){
//do popup stuff
}
</script>
an example in more details can be found by googling. something like this http://istockphp.com/jquery/creating-popup-div-with-jquery/
You should do this in javascript. Especially with jquery library
This should look like this :
<?php
include("control_admin.php");
$sezione = "home_admin";
$canc_id = $_GET['canc_id']; //i'm gessing this is the ID to delete ?
?>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
<script>
$(document).ready(function() {
$('#ok').click(function(){
if(confirm('Are you sure ?')){
$('#form').submit();
}else{
return false;
}
});
});
</script>
</head>
<body>
<?
if(isset($_POST['action'])){
if($_POST['action'] == 'deleted'){
$id = $_POST['id'];
$sql = "delete from table_name where column_id = ".$id;
mysql_query($sql);
echo $canc_id . ' has been deleted!';
}
}else{
?>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post" id="form">
<input type="button" id="ok" name="ok" value="Delete">
<input type="hidden" id="action" name="action" value="deleted">
<input type="hidden" id="id" name="id" value="<?=$canc_id?>">
</form>
<? } ?>
</body>
</html>

Two buttons in a form with different functions

I just wanna ask how can I make a form with two buttons that do different functions? Like for example: I have this table with checkboxes and when a checkbox was checked and a certain button was clicked, the button will perform its assigned task.
Button1 can add, button2 can delete.
Can you help me again, please? I'm kind of new at this and I really want to know. Thank you!
This is more of a JavaScript question than PHP.
You'll need to add an onclick to your buttons:
<input type="button" onclick="functionA();" value="button a" />
<input type="button" onclick="functionB();" value="button b" />
Then create these functions in JavaScript:
function functionA()
{
// do stuff
alert("add");
}
function functionB()
{
// do stuff
alert("delete");
}
Here's a basic example of where you can stick your JavaScript etc:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Example</title>
<script type="text/javascript">
function functionA()
{
// do stuff
alert("add");
}
function functionB()
{
// do stuff
alert("delete");
}
</script>
</head>
<body>
<input type="button" onclick="functionA();" value="button a" />
<input type="button" onclick="functionB();" value="button b" />
</body>
</html>
If you are looking at a server side solution, you can have two submit buttons in the form with different name attributes and then check the $_GET['buttonName'] or $_POST['buttonName'] variables depending on your form submission method.
For example:
<form action="action.php" method="post">
<input type="text"....blah blah />
....
<input type="submit" name="add" value="Add" />
<input type="submit" name="delete" value="Delete" />
</form>

submiting form and then executing php code

On basis of the information that the user fills in my form, I want to execute some PHP code. So after the form is submitted, it should have control on the same page and thereafter it should execute the PHP code (and not before pressing submit button). I have used <input type="hidden" value=1 name="hid"/>. When the user clicks the submit button, the value is changed to 0. But its not working. so solution please..
Is this similar to what you are looking for ?
<?php
if (!isset($_POST["submit"]) ) {
if ($_POST["hid"] == 0 ) {
echo "hid is not 0. display form.";
}
?>
<html>
<head>
<script type="text/javascript">
function check_valid() {
document.getElementById("hid").value = 0;
}
</script>
</head>
<body>
<form method="POST" action="<?php echo $PHP_SELF;?>" onsubmit="return check_valid();" >
<input type="hidden" id="hid" name="hid" value="1" />
<input type="submit" value="submit" name="submit"/>
<!-- form elements go here -->
</form>
</body>
</html>
<?php
} else {
echo "hid is now 0, execute the php code";
}
?>
EDIT: added <input type="hidden" name="hid" value="1" /> for clarity. Thanks to andre_roesti for the suggestion

check filename before posting using jquery/ php

I need jquery to check if my posted filename (up_image) is empty or not.
if it's empty i need a div tag to be shown and come with some kind of alert message.
if not, just do the
$("#submit").submit();
<form action="/profile/" method="post" enctype="multipart/form-data" id="submit">
<p>
<label for="up_image">image:</label>
<input type="file" name="up_image" id="up_image" />
</p>
Upload
</form>
$(function() {
$("#post_submit").click(function() {
var fil = $("#up_image");
if($.trim(fil.val()).length == 0) {
alert("Choose a file!");
fil.focus();
return false;
}
$("#submit").submit();
});
});
1: use a standard submit button to submit your form rather than a javascript-dependent link, for accessibility reasons, and to prevent brokenness if someone tries to right-click-open-in-new-window or other similar action on the link. If you want it to look like a link, you can still use a button, just apply some CSS to make it no longer look like a button.
2: use the form.onsubmit event to do validation rather than relying on a submit button click (forms can also be submitted by pressing enter, which may not always generate a button click)
<form id="uploadform" method="post" action="/profile/" enctype="multipart/form-data">
<p>
<label for="up_image">image:</label>
<input id="up_image" type="file" name="up_image" />
</p>
<p>
<input type="submit" value="Upload" />
</p>
</form>
<script type="text/javascript">
$('#uploadform').submit(function(e) {
if ($('#up_image').val()=='') {
alert('Please choose a file to upload.');
e.preventDefault();
}
});
</script>

jQuery manipulating forms

For some reason it's not changing the action of the forum. I have some code to change the action of a form when a button is clicked:
function changeForm(event){
alert("Before: "+jQuery("#franchiseform").attr("action"));
jQuery("#franchiseform").attr("action", "franchisepreview.php");
alert("After: "+jQuery("#franchiseform").attr("action"));
jQuery("#franchiseform").submit();
}
The binding:
jQuery("input.preview").bind("click", changeForm);
The form:
<form method="post" enctype="multipart/form-data" action="franchiseinsert.php" class="insert-new" id="franchiseform">
The buttons:
<input type="button" value="Preview" id="preview" name="preview" id="preview" class="preview" /><input type="submit" value="Insert" />
First off, you need to clean up the
<input type="button" value="Preview" id="preview" name="preview" id="preview" class="preview" />
to:
<input type="button" value="Preview" id="preview" name="preview" />
as an input should not have multiple id attributes and you should not use classes and id's with the same name. This could be one reason why you're having problems. Then I used the following code and the action url was actually changing:
<html>
<head>
<title></title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#preview").bind("click", changeForm);
function changeForm(event){
alert("Before: "+ $("#franchiseform").attr("action"));
$("#franchiseform").attr("action", "franchisepreview.php");
alert("After: "+ $("#franchiseform").attr("action"));
$("#franchiseform").submit();
}
});
</script>
</head>
<body>
<form method="post" enctype="multipart/form-data" action="franchiseinsert.php" class="insert-new" id="franchiseform">
<input type="button" value="Preview" id="preview" name="preview" />
<input type="submit" value="Insert" />
</form>
</body>
</html>
Unless you stripped out too much, it looks like you need to put your "after" call into a function called "changeForm", which is what you are binding to the click event.
otherwise, keep chaining:
jQuery("input.preview").bind("click", function(){
jQuery("#franchiseform").attr("action", "franchisepreview.php"));
jQuery("#franchiseform").submit();
});
It turns out that this is a Firefox / Mac specific bug. It works on other platforms and browsers, but not this specific computer for some reason. It could be an extension conflict or something else, I'll simply use another browser.
