I have a site where each page is actually a parameter of the index.php page.
So the search page is simply: www.mysite.com/?p=search
I created a GET form whose action is the page above (http://www.mysite.com/?p=search). However, when I submit the form, it is actually submitting the GET parameters to www.mysite.com/index.php instead of www.mysite.com/?p=search.
How do I get the form to actually submit to www.mysite.com/?p=search so that I end up with something like:
www.mysite.com/?p=search¶m1=blah1¶m2=blah2#¶m3=blah3
instead of:
www.mysite.com/index.php?param1=blah1¶m2=blah2#¶m3=blah3
?
You can't use a form to make a GET request to a URI with a query string in the action without destroying the existing query string. Use a hidden input instead.
Add <input type="hidden" name="p" value="search"> to your form and set action="/"

loaded page from javascript. tested for GET & POST. Only GET set as expected;
window.location.href = "medications_edit_revised.html?recordId="+id ;
Retrieved and used the data from the GET[]
Reloaded page from SUBMIT as shown below.
<form method="post" action="">
<table id="detailsDivTable">
<?php
$editClass->selectTheRecord();
?>
</table>
<fieldset name="Group1">
<legend>Group box</legend>
<input name="saveButton" type="submit" value="Save" />
<input name="deleteButton" type="submit" value="Delete" />
<input name="cancelButton" type="submit" value="Cancel" />
</fieldset>
</form>`
Tested GET[] & SET[]
if (isset($_GET['recordId']) ) {
$recordId = $_GET['recordId'];
require_once "medications_edit_revised.class.php";
$editClass = new editRevisedClass($DBH, $recordId);
}
if(isset($_POST['saveButton'])) {
Both tested TRUE. Is this normal behavior. I expected the GET[] would have been cleared when the form was POSTed
If yes is there a way to clear the GET before sending the SUBMIT
Thanks
When you set the URL like this:
window.location.href = "medications_edit_revised.html?recordId="+id ;
You have set URL params. Then when you do this:
Reloaded page from SUBMIT as shown below.
<form method="post" action="">
Because the action is empty it'll retain the URL parameters, because that's what empty and (eg) $_SERVER['PHP_SELF'] do - they send to the current URL, params and all.
You already know the URL so just set it as needed:
action="medications_edit_revised.html"
You seem to be confusing POST/GET requests and the PHP $_POST and $_GET superglobal variables.
PHP will populate $_GET with data in the query string of the URL the request was made to.
PHP will populate $_POST with data in the request body of a POST request if that data is encoded using a supported encoding.
It doesn't matter if the request was caused by JavaScript, a form submission, or something else.
Is this normal behavior.
Yes
If yes is there a way to clear the GET before sending the SUBMIT
Submit the form to a URL which does not have a query string.
The URL the form is submitted to will be specified by the action attribute.
If you don't have an action attribute, it will be submitted to the URL of the current page. If that URL has a query string, then so will be the URL that the form is submitted to (and thus $_GET will be populated).
If you want to avoid that, then specify the action explicitly.
Can you please past some of your code?
If you use GET to revice your variable, it gets it from the URL: example.com?name=jesper&lastname=kaae
The differences is:
GET requests a representation of the specified resource. Note that GET should not be used for operations that cause side-effects, such as using it for taking actions in web applications. One reason for this is that GET may be used arbitrarily by robots or crawlers, which should not need to consider the side effects that a request should cause.
And
POST submits data to be processed (e.g., from an HTML form) to the identified resource. The data is included in the body of the request. This may result in the creation of a new resource or the updates of existing resources or both.
You can read more about them here
Suppose my Form codes look like this
URL : localhost/my-url.php
<form action="hello.php">
...bla bla bla
</form>
I will process the data in hello.php and i want to redirect to user to same url after processing (according to above example)
localhost/my-url.php
I know we can use header but i don't know how to get that url from which form was submited :(
Googled but didn't found any use full.
Thanks.
Add a hidden value in your form:
<input type="hidden" name="lastUrl" value="<?php echo $_SERVER['REQUEST_URI'] ?>" />
You now have the URL in $_POST['lastUrl'] data. You need to do it that complicated because $_SERVER["HTTP_REFERER"]; is send by the browser, and not all of them do this reliable.
You should put a hidden field in your form and set its value to current page url.
Then you submit the form and get the value of hidden field.
Then you can redirect user to hidden field (which is actually a URL of the page where you are submitting form) by using javascript or php.
You can use the
$_SERVER["HTTP_REFERER"];
to get the original URL where the form was posted from.
Remember to escape it, if you use it however. ]
Alternatively, you can process the form using AJAX, send process things (redirection) client-side.
Note that form data can be changed and intercepted if you wish to send the URL of the page as form data.
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>
I have html page and I have taken one form in it and other link outside the form .Form is Submitted by POST method,when I submitting form first time its ok and when I click link it pass data by GET method and when I again submit form then it send both GET and POST variable i.e form data and link data both.so what is the reason for that and how can I solve it.My html page is below
<html>
<body>
<form method='post'>
<input type=input name='name'/>
<input type=submit name='submit' value='submit'/>
</form>
<a href='check_global.php?page_number=6'>Page Number</a>
</body>
</html>
Because the form hasn't the action attribute, so it simply reload the page. When you submit it the first time it's all fine, but when you do it after clicking the link, the url is 'dirty' due to the data of the link, so you have both GET and POST values.
You can check wether the POST attribute is set ( if(isset($_POST['name'])) with php), in this case it has been submitted with the form
When you submit the form the second time you see the form parameters + the url parameter of the page (remember you clicked the link with the relative URL 'check_global.php?page_number=6').
To verify the above try this:
<?php
echo 'GET param ' . $_GET["page_number"];
echo 'POST param ' . $_POST["name"];
?>
As you can see you can access both types of parameters during a POST request.
Hope that helps.
Just to make the point, the OP did not indicate that the form was supposed to submit to anywhere but the current page. So just for funsies, here is the same basic idea, but with an action attribute value:
<form method="post" action="">
<input type="text" name="name"/>
<input type="submit" name="submit" value="submit"/>
</form>
Page Number
Notice that I've set it up so that, for whatever reason, the link points back to this same page and so does the form. The result:
First Load: form submit makes request with POST data to blah.php
Second Load: link follow makes request with GET (thanks to the query string) to blah.php?page_number=6
Third Load: form submit, using blank action to indicate that current page is where to post, makes request with POST form data to blah.php?page_number=6, thus having both POST form data and GET URL data.
So your options are to either set the action attribute value to blah.php so that it does not include the query string, or to accept that if you want to avoid the various ways of doing this in favor of having a more modular form (drop it in any page and you know it will post to that address), then to simply have the PHP backend check if $_POST['submit'] is set and if so, handle it like a form post and don't use any of the $_GET logic that might be screwing things up.
The link is never sending the form data as POST, and the POST data is not part of the GET array, so you know that when there is no POST, it's just get and if there is POST, it was a form submit, even if there is a GET array.
Or just use separate scripts so you don't get mixed up.
i have a textbox and i wish to use the value entered in the textbox in controller- onclick of a link(not form submit). So i assume i have to use postlink to submit. But how do i get the value of that textbox in postlink?
following is my code:
<?php echo $this->Form->postLink(
'Get Coords',
array('action' => 'test', $this->request->data['Rideoffer']['PickFrom'])
);
?>
i get an error on $this->request->data['Rideoffer']['PickFrom']. data['Rideoffer']['PickFrom'] is name of my cakephp textbox(i saw it in firfox inspect element).
How do i get the textbox value?
The FormHelper::postLink method has no way of getting a textbox value. The postLink method pretty much just creates an <a> link element that submits a hidden form using Javascript. Here is an example of what postLink spits out:
<form action="/posts/delete/16" name="post_511c870e05d25" id="post_511c870e05d25" style="display:none;" method="post">
<input type="hidden" name="_method" value="POST"/>
</form>
Delete
As you can see, when you click the <a> element, it submits the form with the hidden input. You can change the value of what this input submits by passing in parameters to postLink, but you cannot dynamically get a value of a textbox that a user can modify and submit it with the form without doing something extra.
There are two similar options (one being slightly more Javascript heavy):
1) Since you are using Javascript, you can use Javascript (or jQuery) to dynamically change the value of the hidden input to whatever the user types. Even better, you can do it so the Javascript/jQuery only updates the hidden form input when the user clicks the link. Note it may be easier to not even use the postLink function and do all the form stuff yourself (or with Cake's FormHelper).
2) Don't use the postLink method at all. Create a normal form with the textbox input and mimic what postLink does. Specifically, you wouldn't have a submit button for your form. You would just basically just copy what it spits out.
<form action="test" name="UNIQUE_ID" id="UNIQUE_ID" method="post">
<input type="text" name="data[RideOffer][PickFrom]" value="POST"/>
</form>
Click
Note in the above example you should match UNIQUE_ID as the same value and you must also remove style="display:none;" from the <form> tag.
