So, I have a form which I submit once and redirect it withing the same page and after the refresh I execute some scripts on the data.
For ex, if my page is index.php I can summarise it like this:
<?php
if(isset($_POST['msg']))
{
//do smth
}
$_POST=array();
?>
<html>
....
<form action="index.php" method="post">
<input type="text" id="msg" name="msg">
<button type="submit">Submit</button>
</form>
....
</html>
The problem is that after the first submission, the POST variable regains its initial value after every page refreshment even though I delete it every time and I don't resubmit the form.
So what should I do?

Is there a way to submit a form like this without refreshing the page and going to the first page, for example if we have two pages, this code will make the page refresh to the first page. I have suggested to use ajax, but I was turned down.
<form action="/page.php?pageAction=POSTS&pageID=1&subPageID=2" method="post" name="page" id="addPageLink" enctype="multipart/form-data">
... The Form Code goes here
<input type="submit" class="mt_btn" name="frmAddLink" id="addPageLink" value="Post">
</form>
I have thought about adding the page to the action like this, so that if the page refreshes, at least it refreshes on the same page.
<form action="/page.php?pageAction=POSTS&pageID=1&subPageID=2&pagen=2" method="post" name="page" id="addPageLink" enctype="multipart/form-data">
... The Form Code goes here
<input type="submit" class="mt_btn" name="frmAddLink" id="addPageLink" value="Post">
</form>
Is this even possible? will messing with the action by adding hashes affect anything?
I have a simple form. I am sending the form to same page that has the form. However, after every submit process, then when I want to refresh the page manually, the browser asks me:
Do you want to re-send the form?
How can I prevent this?
foo.php
<?php echo $_POST['id']; ?>
<form action="foo.php" method="post">
<input type="text" name="id" value="">
<input type="submit" value="Send">
</form>
Thanks!
check with a condition if the form was posted, process the form and then redirect using javascript.
<?php
if (!empty($_POST["id"]( {
//do stuff
?>
<script>
location.href=("/");
</script>
<?
}
?>
Method 1: Check with a condition if the form was submited and then redirect to the same page.
if(isset($_POST['button_name_from_form'])) {
#...code
header('Location:page.php');
}
!! But make sure that header is before any output. !!
Method 2: Ajax
I have my page as follows:
<form id="filterQuery" action="#" method="post">
...
<input type="submit">
</form>
<?php
// use $_POST to determine query restrictions and conditions
?>
Now my problem is with the action of the form, because if I make it "#" self, nothing happens when clicking submit.
I'm using a template which shows subpages as include in <div>s. In other words, my page is not a standard HTML page which contain <head> and <body> etc, but is in the following format: basic.php#!/my_sub_page.
Trying to make action "basic.php#!/my_sub_page" results in an empty _POST
I tried your example and everything works fine with /index.php#!/smth in action and post variables.
<form action="#!/something" method="post">
<input type="text" name="var1" value="123">
<input type="submit"></form>
<?php
print_r($_POST);
?>
This is how I check it.
Are you sure you didn't forget name attributes in inputs?
Do you see their values in url after ? if you change method to get?
what I am trying to do is to create a from, and execute a php script after the submit has been pressed. the problem seems to be that the page of wprdpress with the form and the code gets executed all at once.
If I put the code below into a regular test.php file on my server, it does what it is supposed to do (echo "Form Submitted!") after I click submit. However if I put the same code in a page template or a wp page it spits it out all at once (the form, and the "form submitted).
<html>
<head>
<title>Notify on Submit</title>
</head>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<label>Name: <input type="text" name="name" /></label>
<input type="submit" value="Submit" />
</form>
<?php if (count($_POST)>0) echo "Form Submitted!"; ?>
</body>
</html>
I have no idea why this is like that, and would really need some help on this.
What I have also done is to create two different wp pages(one goes to the other). It works, but will create a bit of a mess. I would like to do this in one page.
page 1
<form action="page2" method="POST">
Your form input.
<input type="submit" name="submit" />
</form>
Page 2
<?php
if (count($_POST)>0)
{
echo "Form Submitted!";
unset($_POST);
$_POST = array();
}
else echo "Form has been reset!";
?>
Probably there is another form on the Wordpress page using the POST method. Instead of checking for $_POST > 0 (which will only tell you that something was posted) add some identifier to your form, and check for that so you can tell if your form was posted.
A simple way to do this is with a hidden input:
<html>
<head>
<title>Notify on Submit</title>
</head>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<label>Name: <input type="text" name="name" /></label>
<input type="hidden" name="whatform" value="myform" />
<input type="submit" value="Submit" />
</form>
<?php if (isset($_POST['whatform']) && $_POST['whatform'] == 'myform') echo "My Form Submitted!"; ?>
</body>
</html>
I think you just need to remove the php from your action. The action defaults to the current url on any form.
PHP_SELF refers to the file path - thats why it works when you do it on just a solo file. As part of the wordpress application, you can't run files directly - you have to reach that url.
Remember that WP uses actions and hooks, and so if you put code "in a WP page" or "in a template" it may fire at various times. You might get an echo statement that fires something to the screen before the content comes out. Consider putting all your output within filters, actions and hooks.
Your logic seems to depend on the post count. Consider using a unique name, i.e. the name of the submit button on your form. Check for if(isset($_POST['my-unique-submit-button'])). Is anything else in WP submitting via post? You might not know!
I am testing Html form using post method and got this odd result:
I have two html pages on server apache (already installed php): post.html and target.html, and the code for these page are followings:
post.html (don't worry about the html standard)
<div style="text-align: center">
<form method="POST" action="target.html">
<input type="text" name="testname" value="sometext" />
<input type="submit" value="submit" />
</form>
</div>
and target.html
<html>
<head>
</head>
<body>
<h1>Target page</h1>
</body>
</html>
When I entered data to the form on post.html page and hit submit button, I got to the target.html page. When on this page(target.html), I refreshed the page, and what I receive is a blank page. The second time I refreshed, It turned to normal Html page.
I don't know why it returned a blank page the first time I refreshed, I have tried the same approach but with PHP page, and the content of target page (assum name target.php) still remains (not blank like html files above)
So, could you explain me about this problem?
Thank you.
This definitely has something to do with your browser. Same here on a mac using Safari, on some pages after submitting the content, the page seems to freeze, I refresh it, and then it works again.
Definitely not a code problem, as far as I'm concerned.
It's because you cannot pass an input from html to html file. Your target.html should be a php file (target.php).
and try to put this code on your target.php
<?php
var_dump($_POST); //this will show the inputted text and also show the data type and will stop the code execution here. other codes below will not be executed.
echo $_POST['testname'];
?>
Additionally, change target.html to target.php in your form action
First I will start out by correcting your post.html
<div style="text-align: center;"> <!-- added a ; after center -->
<form method="POST" action="target.html">
<input type="text" name="testname" value="sometext" />
<input type="submit" value="submit" />
</form>
</div>
that may not matter but you should end all your styles with ;
To continue, everything looks fine. maybe something weird happened between refreshes.
save your form page in php than add the php script in the same page, here try this. remember save in .php.
<?php $testname = $_Post['testname'];
echo $testname ?>
<div style="text-align: center">
<form method="POST" action="">
<input type="text" name="testname" value="sometext" />
<input type="submit" value="submit" />
</form>
</div>
