I have this javascript line
<script type="text/javascript">document.write(top.location);</script>
and this code
<form action="rating.php" method="post">
<input type="hidden" name="url" value="xxxx" />
<input type="submit" />
</form>
<?
echo $_POST["url"];
?>
Please, How i can add the value of javascript (xxx) in the hidden field?
Also does it possible to let <input type="submit" />have automatic submit ?
Thanks
Do you mean this, in order to feed the hidden field?
<input type="hidden" name="url" value="<? echo $_POST["url"]; ?>" />
Regarding submit, you can use javascript to handle the submit event:
If you add the attribute name="FORMNAME" inside the <form ... > tag, you can use:
document.FORMNAME.submit();
for submitting the form, without using the submit button.
In order to feed a hidden field through javascript, use:
document.FORMNAME.url.value = top.location;

I want use that form for change image but without click to submit.
<form action="chav.php" method="POST" enctype="multipart/form-data" >
<label for="fileup"><img src="/images/img-ico.png"/>Aggiungi Foto</label>
<input type="file" name="fileup" id="fileup" /><br/>
<input type="submit" name='submit' value="Upload" />
<input type="hidden" value="<?php echo milldigital_filter('get',$_REQUEST['pg']); ?>" name="pg" />
</form>
so when i select image, directly submit without press any button.
You can submit form using javascript within form event attribute onchange:
...
<input type="file" name="fileup" id="fileup" onchange="this.form.submit()" />
...
When browser render form element with onchange property it starts to observe if its value changes and execute javascript code when it does. It changes when you select file. documentation
this.form means we'll refer to form object that this html (form) element belongs to. Then execute its submit() method.
i am submitting form using get method to a url which already contain parameter like
localhost/myfile.php?section=console
my form code is
<form method="GET" action="<?=basename($_SERVER['PHP_SELF'])?>/section=console">
<input type="text" name="cmd" />
<input type="submit" value="execute" />
</form>
when i submit this data through post type it submit data then it submit like myfile.php?cmd=blahblah
but i want to submit it to myfile.php?section=console&cmd=blahblah.
i can do this by using hidden field but i am insearch of other better way
Simply add a hidden field into your form
<input type="hidden" name="section" value="console">
If you are not interested in using hidden fields then rewrite your form like this
<form method="GET" action="<?php basename($_SERVER['PHP_SELF']) ?>/?section=console">
You should use a hidden input within your form
<form method="GET" action="<?php echo basename($_SERVER['PHP_SELF']); ?>">
<input type="hidden" name="section" value="console">
<input type="text" name="cmd">
<input type="submit" value="execute">
</form>
How do I pass hidden information about a form?
<form action="index.php" method="post">
<textarea rows="2" cols="30" NAME="com" >
</textarea>
<input type="submit" name="com_submit" value="com" />
</form>
I need see that the comment is passed for which type of post so I need to pass the value of variable $type also by this form so how should I do that?
I am a beginner so i am sorry if i am asking any stupid question?
Use a hidden field:
<input type="hidden" name="form_type" value="theFormType" />
The user will not see hidden inputs on the form.
If the value of the hidden form comes from php, you can use this:
<input type="hidden" name="form_type" value="<?php echo $type ?>" />
if i understand correctly you want to use the hidden input
hidden input a great summary from w3schools
I have a basic form that I am using as a dummy to test some JavaScript functionality. My goal is to click the submit button and have submission paused until a javascript function is executed, then submit the form after that. the code I currently have is below, but the submission of the form is not prevented, and the hidden field's value is never set. can someone explain why this is happening?
NOTE I am aware of a jQuery method of performing the same functionality. I am specifically trying to solve this problem without using jQuery. If your only answer is "jQuery is better", please do not bother.
<html>
<head>
<script type="text/javascript">
function test(){
document.getElementById("hidden").value="hidden";
var queryString = $('#decisionform').formSerialize();
alert(queryString);
document.getElementById("form").submit();
}
</script>
</head>
<body>
<?php
if ($_POST){
foreach ($_POST as $key=>$value){
echo "<b>$key</b> $value<br>";
}
}
?>
<form action="hello.php" method="post" id="form">
<input name="first" type="text" />
<input name="second" type="text" />
<input name="third" type="text" />
<input name="hidden" type="hidden" />
<input name="submit" type="submit" value="Submit" onclick="test();return false;" />
</form>
</body>
</html>
You don't have an element with the id hidden so document.getElementById("hidden").value="hidden"; will throw an error as you can't set properties on undefined. The script will stop running and never reach return false so the form will submit as normal.
try <form action="hello.php" method="post" id="form" onsubmit="test(); return false;">
to prevent a submit, you actually need to have a return false, in the onsubmit even of the form itself
along with not having an id on the hidden field.
<input name="submit" type="submit" value="Submit" onclick="test();return false;" />
use a regular button in this case because your function is performing the submit.
<input name="submit" type="button" value="Submit" onclick="test()" />
You're missing the id attribute from your input element. Modify <input name="hidden" type="hidden" /> to <input name="hidden" type="hidden" id="hidden" />.
You can use
onclick="return test()"
and just return false at the end of the function.
Add id="hidden" to your input, like this:
<input name="hidden" type="hidden" id="hidden" />
I'm trying to build a form using php & jquery, but I'm a little confused as to what to do with the jquery portion of it...
Basically, when the user submits the first form, I want to direct them to the "next step" form, but I want to retain the values submitted from the first one in a hidden input field...
If someone can either show me how or point me to a good tutorial, I'd appreciate it...
I don't have any of the php or jquery yet, and this is just a simplified version of the html markup...
//first.php
<form name="form1" method="post" action="second.php">
<input type="text" name="name" value="" />Name
<input type="submit" name="step1" value="Next" />
</form>
//second.php
<form name="form2" method="post" action="process.php">
<input type="hidden" name="name" value="{$_POST['name']}" />
<input type="text" name="message" value="" />message
<input type="submit" name="step2" value="Finish" />
</form>
<input type="hidden" name="name" value="{$_POST['name']}" />
should be,
<input type="hidden" name="name" value="<?php echo $_POST['name']}; ?>" />
and also sanitize the input, if you want
I don't no if there is a better way to do that.
But, when I need to do such thing, I do in this way:
<script>
<?php
foreach($_POST as $key => $valule)
{
echo "$('$key').val('$value')";
}
?>
</script>
So, in your nextstep file, all you'll need to do is set up the hidden fields and then just loop through the post vars and set each one via jquery.
