Submit button showing in GET URL - php

I'm having a problem with my HTML GET form that's connected to a PHP script, so, basically, when the action is done I see the SUBMIT button value in the URL, so it's like this http://url.com/?valueI=Want&submit=Submit+Value.
How do I stop that from happening?

Remove the name attribute from the submit element to prevent it from being passed in the query parameters.
See: Stop the 'submit' button value from being passed via GET?

This is the nature of GET requests. The submitted values, aka Query String, are shown as part of the URL after a ? suffixing the page URL.
If you don't want it to show up, use POST method, or make a script that submits using Ajax.
Now if the question is only about the text in the submit button being shown, if you don't want it to get submitted along with the rest of the form all you have to do is not give it a name.
<input type="submit" value="Send Form">
No name="..." in the tag.

you need to set the form method
<form action"/your/path" method="post">
...
</form>

You can use button tag to submit the value using GET method.
<button type="submit">Submit</button>

do something like:
<form action="myfile.php" method="get">
(your form elements here)
<input type="submit" value="Submit" />
</form>

form type="url" POST to PHP

So I have a form that requires a user to submit their website to a form. Here is the html line:
<input type='url' name='link'>
And I'm using <input type="submit" value="submit" formmethod="post"> to submit the form to a php
And I'm trying to retrieve the values in my php file with:
$link = $_POST['link'];
Why isn't this working? At first I thought it was because I had htmlspecialchars() but it's not coming through without it either. I can't find anything in any google search that even mentions anything related to this kind of problem (with a type="url" form)
What do I need to do to process form data with type of "url" in PHP with a $_POST?
Get your form method to be set to post e.g
<form method=post>,
if you submit the form and in the url in your browser u can see some more inf then be sure 2 check your form method
I think this is wrong,
method="post"
Its only method, not formmethod
Also make sure, you dont have one more for element name with link.

How do I submit my form using href?

Am using this onclick='document.forms['form_name'].submit(); return false;' but this doesn't work as am having href=results.php?page_no=1 etc, has dynamic links, examples show to make this work I need to use href="#" but any idea how I can submit the form and than navigate to page2? Because I want to save the check box values in a session
Add class to your hrefs (class="pagination") and id (id="form") to your form. Then you can use Jquery framework for this stuff.
$(".pagination").click(function(){
// get page id, set form action with params
$("#formId").submit();
return false;
});
You have a bad design.
You can't perform multiple competing actions on a form click and expect it to work.
You need to either let the link be clicked and let it load another page, or if you are just setting some session variable (although it would be far better to set this with a querystring parameter or a cookie), you can use an Ajax request to send that off asynchronously.
Here I substituted page2 with Google just for test
Submit
<form method="get" action="https://www.google.com/search?q=test" name="test">
<input name="Checkbox1" type="checkbox" />
</form>
edit:
Submit
<form method="get" action="" name="test">
<input name="Checkbox1" type="checkbox" />
</form>
without encodeURIComponent(this.getAttribute('href') the parameters are missed.
Some options:
1) Use jQuery AJAX, serialize and post the form data and then redirect (location.href) on the onSuccess callback. Something like this:
$.post("submitform.php",
$("form").serialize(),
function(data){location.href='results.php?page_no=2';}
);
2) Post the form to a named hidden iFrame using "target" on the form tag. If this is really just a best effort sort of recording you shouldn't need to wait for the page to load, the request should be enough and you can continue to the next page. Something like this:
<iframe="targetname" style="display:none;" />
<form name="myform" target="targetname" method="post" action="submitform.php">
....
</form>
<a href="page2.php" onClick="document.forms['myform'].submit(); return true;">
Click Here
</a>

Send form results to another page php mysql

Hello I have a form working properly using
php echo $_SERVER['PHP_SELF']
The results are shown on same page as form.
I need to be able to send the form data and results to another page (eg results.php) when the user submits the form.
How is this achieved?
Just point the form action to results.php
<form action="results.php">
<!--Inputs-->
</form>
Or if you need to do a redirection store $_GET at $_SESSION['parameters'] .
Here are some attributes of form tag <form> you need to set them..
<form action="controller.php" method="post">
<!--form elements-->
<input type="submit" name="submit" value="Submit Form" />
</form>
Here when ever the submit button clicked, it will submit the form to its action i.e. controller.php by post method (i.e. form elements' value won't display in query string).
Later you can access their value on controller.php by $_REQUEST['element_name'] or $_POST['element_name'] or $_GET['element_name'] according to the form method type.

Basic Javascript: onclick event not working

Given this simple javascript function:
function update_cart() {
alert("--update--");
document.form1.command.value="update";
document.form1.submit();
}
and this button at the bottom of my form:
<input type="submit" value="Update" onclick="update_cart()" />
The data in the form is 'submitted' to the new URL. but the update_cart function is never called. I know because I never get an alert box, and the URL reads...?c=Albania&m=....
Also, the form element
<input type="hidden" name="command"/>
does not get posted to the URL, either. URL reads ?command=&c=Albania...
I have tried the following: changed onclick to onsubmit, checking $_REQUEST variables, cutting and pasting the code from known working pages.
I'm at my wit's end, and would be grateful for any help!
Oh, yes: same behaviour in firefox 6, Opera 11.5, & IE7. I'm running WinXP SP3.
Thanking you,
Sadhu!
Once try
<input type="button" value="Update" onclick="update_cart()" />
instead
<input type="submit" value="Update" onclick="update_cart()" />
if you want that for 'submit' type then go with 'Allen Liu' answer
enter code hereif you wane to change sth when onsubmit, you need to do these changes before form's submitting. so you need to add these opeartion to the "onsubmit" event of the form, rather than the "onclick" event of the submit button.
like this:
<form name="toSubmit" onsubmit="update_cart();"><input type="submit" name="btn" value="hello"/></form>
If you want the script to run on submit of form, use:
<input type="submit" value="Update" onsubmit="update_cart()" />
The onsubmit event is usually used to run some validation script. If the validation returns true, the form will submit. If it returns false, the form does not submit. In your case, the script is coded to submit the form so no return boolean value is necessary.
Otherwise, I would not give your button the submit type if it really doesn't submit the form. You can simply use button tags with the onclick and that should work:
<button onclick="update_cart()">Update</button>
First of all there is no need to change your html; see my demo.
On every click on a submit button, first the click-handler (if exists) will be started, then the submit-handler (if exists) (which should be in the form tag) and then the action of the form will be executed. This procedure will be only stoped, if a handler returns false.
But why will your javascript function update_cart not be called?
I think it could not be found, but I don't why. Can you bind the function to the window dom element only for testing (like in my demo)?
P.s.: you don't need to submit the form in your click-handler (if you don't return false). You can remove the line: document.form1.submit();.
P.s.: it will be better not to use a click-handler on the submit-button, instead use a submit-handler in the form tag (see my demo2).

How to check if a form is submitted via javascript?

I have this conventional submit button which submit a form like this:
<form method="post" id="form_submit">
...
<input class="button" type="submit" name="Submit" value="Submit">
</form>
And I check if the submit button is clicked using this:
if(isset($_POST['Submit'])){
//update DB
}
Now I have a submit link using jquery:
Submit
JS code:
$("#form_submit").submit();
What is the alternative way here to be used here for if(isset($_POST['Submit'])) since I'm submitting the form using javascript?
If I understand you correctly, try this:
if ($_SERVER['REQUEST_METHOD'] === 'POST')
{
// your code.........
}
You should add a hidden input <input type="hidden" name="formsubmit" value="yes" /> to the form which will always get submitted, and check for that instead of the button (which only gets submitted if it is clicked on ..)
If I understood your problem correctly that you can simply change input type to hidden.
<form method="post" id="form_submit">
...
<input type="hidden" name="Submit">
</form>
$_POST['Submit'] variable will be defined.
The best solution is "Don't do that". If you want to submit a form then use a submit button (don't do it as a side effect of clicking on a hyperlink to the top of the page). Any JavaScript you want to run can then be handled in the form's submit event.
If you really want to do it as a side effect, then check for the existence of any other field that you know will be set. You could add a hidden field to ensure there will be one of a given name/value combination if you like.
