I need to submit a form to the URL /search/, without any variable names. So that if I input into the form 'foobar', It will then submit the form in GET format to /search/foobar.
How can I achieve this? As far as I can see there is no way to do it with HTML, i'll have to use jQuery.
<form action = "/search/" onsubmit="this.action += encodeURIComponent(this.term.value); this.term.disabled = 'disabled'">
<input type="text" name="term">
</form>

I'm trying to add a value to $_POST data while it gets submitted to the target page as follows:
post.php
<?php $_POST['field1'] = "Value1";?>
<html>
<head>
</head>
<body>
<form method="post" action="catch.php">
<input name="field2" type="text"/>
<input type="submit" value="Submit" />
</form>
</body>
</html>
catch.php
<?php
foreach ($_POST as $key => $value) {
echo $key . " : ". $value;
echo "<br/>";
}
?>
but I cannot catch 'field1' on the other end. I don't want to use a hidden input field. How can I achieve that?
Thanks!
When you send the form, the $_POST data is reset and assumes only the inputs inside the form and a possible query string you may have appended to form action.
The best way to accomplish what you want is using hidden field but since you dont want it, you can append a query string to your form action:
<form method="post" action="catch.php?field1=Value1">
You're not submitting field1 anywhere. What happens is this:
post.php generates a HTML page (one that doesn't contain any reference to field1)
the user's browser renders the page
on submit, only the elements inside the form are submitted
catch.php receives the elements submitted above.
In other words, you need to get that value into your form:
<form method="post" action="catch.php">
<input name="field2" type="text"/>
<input name="field1" type="hidden" value="<?php echo htmlspecialchars($_POST['field1']) ?>"/>
<input type="submit" value="Submit" />
</form>
There is no other way to get the value into your POST data, if it's not present in the form. What you could do as a workaround is store the data in GET (size limit), session (concurrency issues - what happens when the user has two tabs open, each with different session data?), or cookies (size limit AND concurrency issues).
You can't do it this way. If you want to send the data you're trying to add to the POST there only through the users form, you are forced to also store it somewhere client side (e.g. a hidden field or a cookie). What you're doing right now is setting some value into the POST variable, but it gets overridden by the users form post (or rather the $_POST variable you're using after the form post is another instance).
What you could do instead to keep it serverside is save the value in the variable to the session of the user, then in the form post action server side get the value again (given the fact that you're using sessions). Lastly you could just store it in some table in a database, though I wouldn't do this.
Since $_POST are data sent by post method to script, you can not use it for another request directly. You need to compose and send another post request. The easiest way for you will be to use hidden input field/s.
Or you can choose another approach to make http post request, for example curl methods.
If you don't need data to be given by post method, you can save it in session, for example.
try this:
in post.php
<?php $_SESSION['field1'] = "Value1";?>
<html>
<head>
</head>
<body>
<form method="post" action="catch.php">
<input name="field2" type="text"/>
<input type="submit" value="Submit" />
</form>
</body>
</html>
in catch.php
<?php
if(isset($_SESSION['field1']))
{
$_POST['field1'] = $_SESSION['field1'];
unset($_SESSION['field1']);
}
foreach ($_POST as $key => $value) {
echo $key . " : ". $value;
echo "<br/>";
}
?>
Make sure you have started the session.
Note: you must use hidden elements or query string as other user suggested.
I am try to get the value of the input field with a custom attribute I have created using PHP. This is my code:
<form action="uploadform.php" method="post">
<input type="text" name="email" id="email" mynewattribute="myemail">
<input type="submit" name="submit">
</form>
//uploadform.php
<?php
//I know $name = $_POST['email']; will give me the value but I would like to get the value of the input field with "mynewattribute" and not name. Is it possible?
?>
The web browser doesn't know what to do with your custom attribute, so will simply ignore it. The only data sent when you submit the form is the values of "successful" elements. So your custom data will never be sent, and can never be read by the receiving script.
The best place to put such data is into hidden input fields. One possibility is to use names with square brackets in, which PHP automatically converts into arrays. e.g.
<input type="text" name="email[value]">
<input type="hidden" name="email[magic]" value="true">
Populates an array like this:
$_POST['email']['value'] = '';
$_POST['email']['magic'] = 'true';
When I create i form - I do something like this:
<form name="form-name" method="post" action="?<?=$_SERVER['QUERY_STRING']?>">
[...some elements...]
<input type="submit" name="form-name" value="button">
</form>
Now I need to get the value of the name="" of the submit button, and not the actual value="".
In this case : "form-name".
And here's why:
When I submit a form; I write the action to database - and therefor need the name of the form submitted.
I know I can just have a hidden field with the form name. But I would like to make it simpler by just extracting the name from the submit button because I have a couple of other hidden form elements that I need to add on every single form I create to make my template system work.
And no javascript...
So, let's say your HTML form is this:
<form name="form-name" method="post" action="">
<input type="submit" name="form-name" value="button">
</form>
And you want to get what is inside name="form-name" in this case the form-name
Well, then in the PHP side you can, treat the $_POST global as associative array, and extract the key from it like this:
<?php
if(isset($_POST)){
foreach($_POST as $key=>$each){
echo $key; // this will output "form-name"
}
}
I might have come up with a solution to my question...
Here's a example form:
<form name="vehicle-vinNr" method="post" action="?<?=$_SERVER['QUERY_STRING']?>">
<input type="hidden" name="hello" value="world" readonly>
<input type="text" name="element">
<input type="submit" name="vehicle-vinNr" value="send">
</form>
First I need to extract and place the element-names into a new array:
<?php
if ($_POST){
foreach($_POST as $_FORM_ELEMENT_name => $_FORM_ELEMENT_value){
$_FORM_ELEMENT_names[] = $_FORM_ELEMENT_name;
}
}
?>
In this case the array now contains:
hello
element
vehicle-vinNr
If the submit-button is, and always is, the last element in the form - this would work:
$_FORM_name = end($_FORM_ELEMENT_names); // vehicle-vinNr
But sometimes the submit-button is not the last element, so I needed to make a change:
If I always start the name of the submit-button with submit_ - e.g. submit__vehicle-vinNr or with multiple submit buttons for different actions like submit_update__vehicle-vinNr/submit_delete_vehicle-vinNr I can just do this:
if ($_POST){
foreach($_POST as $_FORM_ELEMENT_name => $_FORM_ELEMENT_value){
if(strstr($_FORM_ELEMENT_name,'submit_')){
$_FORM_ELEMENT_submit_name = explode('__',$_FORM_ELEMENT_name);
$_FORM_name = $_FORM_ELEMENT_submit_name[1]; // vehicle-vinNr
}
}
}
This is the solution I came up with - any thoughts?
Right now I am updating user_list List using jquery and submitting the form data using Ajax
now I want to submit that form like normal form submit
Here is the problem I am unable to pass the JQuery updated user_list along form ?
Is There any way to do this ?
What I have tried
<script>
var user_names=[];
function check_selected(id){
user_names.push(id);
$("#username").val(user_name);
}
</script>
Where username is a form field like
<input type ="hidden" val = "" id="username" name ="username">
val is not a valid attribute for the <input /> element. Change it to value
<input type="hidden" value="" id="username" name="username" />
I am not sure if this will help or not, but you have used a variable that may have not been initialized
$("#username").val(user_name);
should be
$("#username").val(user_names); //missing s
besides, if you are after sending an array to the server, and the server is php, I would suggest adding [] square brackets at the end of the field name, this is a clean way of sending the list and the server can build the array and you would be able to access it as a list
$_POST['list_name'][index]
Try this
<script>
var user_names=[];
function check_selected(id){
user_names.push(id);
$("#username").val(user_names.join(","));
}
</script>
I'm using jcrop to crop my photos and need to send the current values along with my form submission. Is there an easy way to do this?
The JavaScript variable is this:
c = coords;
$.param(c)
Can I include this as a hidden field in my PHP form somehow?
<input type="hidden" name="coords" value=" ??? " />
Of course you can:
<form onsubmit='document.getElementById("your-hidden-field-id").value = c.toString(); return true;'>
...
<input type="hidden" name="coords" id="your-hidden-field-id"/>
</form>
