Is it possible to hold the get params. in the url by switching pages?
Situation:
At the first page the user can choose between different prices.
The "submit" button is just an easy
<a href="/genrepage?price=twoDollars" value.....>
So the user does get directed from the ".../pricepage" to the ".../genrepage?price=twoDollars" url. At this point it is possible to choose between different genres. The submit button is in a ..
<form method="get" action="">
<input type="submit" name="genre" value="action">
</form>
..now the user does get redirected to the ".../genrepage?genre=action" url.
I would like to see something like ".../genrepage?price=twoDollars&genre=action.
Is it possible to realise this via WordPress (only) or would I need to code "smthg like a" plugin with php? Or is the price get param. saved in the $_Session so I could call it anyhow in the functions.php?
(Sry for this english and my bad knowledge, still learning^^)
You are obviously a web dev noob but we all have been in earlier times 😉 well in case you have a session opened (WordPress does not use sessions by default) you simply could do:
$_SESSION["price"] = $_GET["price"];
You also could start a session if none exists by adding
session_start();
in the beginning of your functions.php file.
The get variable is saved to the session then and will be available in your functions.php (and elswhere) as long as the session is alive. Save into your session whatever get/post variables you want.
If you are not using sessions you could put the price value into a hidden field at the form in the second page:
<form method="get" action="">
<!-- ... your other fields ... -->
<input type="hidden" name="price" value="<?php echo htmlentities($_GET["price"]); ?>" />
<input type="submit" name="genre" value="action">
</form>
Then on the next page both variables will available in $_GET.

I'm trying to create a cookie for a web page. The cookie value will vary based on the users name. Does PHP have an input type function? I just want to add an input field to the page an then the PHP will use that to define the users name for the page. I have the create cookie code, just can't figure out how to get the name from the screen and insert it to the cookie code. Appreciate any suggestions. This is on a WP website.
Not natively because php does not execute in browser, it executes on your server, but it can be used to write an HTML input.
The syntax would look something like this:
echo '<input type="text" name="myinput">';
or
?>
<input type="text" name="myinput">
<?php
You would then use a form post, CURL, or AJAX function to send the data back to the server where a second PHP script would process the input.
That said, it would help to post your create cookie code, since you may not even need to send it back to the server, but just handle it all in the browser using Javascript in which case your submit button only needs to pass the input to a Javascript function instead of posting it.
Is this something you are looking for?
Here it just takes the value user input from the browser and set it as a cookie
<?php
if(isset($_POST['name']) && !empty($_POST['name'])){
setcookie('setcookie_name',$_POST['name']); // setting cookie
}
?>
<form action="" method="post">
<input name="name" value="" placeholder="Enter your name" />
<input name="submit" type="submit" value="Submit"/>
</form>
I am looking for a bit of code to do the following:
A form containing a single text field and a submit button, must send the value of the text field to a landing page that automatically counts how many html tags that this page contains.
E.g. if the text field states stackoverflow.com, the landing page should say (H1 tags = 20) with many more parameters to come.
How is this done? I know how to make a form, but I do not know how to make it send its value to the landing page.
<form action="landingpage.php/" method="post">
The URL
<input type="text" name="cf_name">
<input type="submit" value="Submit">
</form>
This piece of code is a perfect answer to your question.
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="GET">
Type In Something: <input name="random-info" type="text" size="25">
<input type="submit" value="Submit">
</form> <br>
<?php
echo "You Typed: " . $_GET['random-info'];
?>
you get the method into the url, then you can use them on another page.
To access data from a form it depends on the method. Since your code shows a post message you simply access it in the php on the landing page by user $POST_['cf_name'].
To learn more you can check out:
http://w3schools.com/php/php_post.asp about the post method and http://w3schools.com/php/php_get.asp about the get method.
Also an invaluable source is php manual itself.
As far as counting the tags, not really sure what you are trying to achieve.
If you are counting the tags in the page you create, just make a variable and add to it each time you put that specific tag on the page.
Then you can put those values in a hidden field of the form to be passed into your landing page.
I have come across a situation I am not sure how to hndle. I am new to this, but I do understand the server side realm of php vs user side of the browser.. I just dont know how to accomplish what I want to do..
I have a form on a page where a user can enroll in a school course. They select the course type, location, date, and payment type.
On submit it goes to an outsourced shopping cart for payment, which uses PHP vars to populate the item description, price, ect.. along with our store id and other pertinent information.
I ALSO need to insert some of the PHP vars into the user database.
I tried having the form action go to another PHP page which process the DB entry then redirects to the cart, but when I get to the cart an error is generated saying the info was not submitted properly.. but the DB entry was successful.
I also tried using an include(dbentry.php) in the form action with the cart link.. this generates a server side error on loading the page.
At one point I successfully had it create a db entry (although it was blank) AND successfully redirect to the cart with all of the vars there, but a blank DB entry does me no good. I am assuming entry happened before the $POST vars were created... I also have changed so much I dont remember how I did it and cannot reproduce that..
My main question is:
How can I have a user fill out an HTML form, and when submitted perform the DB entry with the $POST vars while also directly passing the $POST vars to the cart page? Normally I would run the dbentry.php on the next page, but I have no access to scripting on the outsourced cart page...
You can try to use hidden textboxes to hold the values of the form! And this value can be accessed from different php pages
You will need to pass your variables from page1.php to page2.php to outsourced cart. I would do something like the following:
What the below code is doing:
Send original form data using POST to page2.php
Page2.php will then read the POST data (you can now do what you want with this data, whether it be store it into a database, etc.). A Javascript snippet will then submit the form to your checkout cart page (page3.php) with the necessary POST variables which are being stored as hidden fields within the form.
Page1.php
<form action="page2.php">
<input type="text" name="myfield1"/>
<input type="text" name="myfield2"/>
<input type="text" name="myfield3"/>
<input type="hidden" name="myfield4"/>
<input type="hidden" name="myfield5"/>
<input type="hidden" name="myfield6"/>
<input type="hidden" name="myfield7"/>
<input type="hidden" name="myfield8"/>
</form>
page2.php
<?php
if(isset($_POST['myfield1']))
{
$myfield1 = $_POST['myfield1'];
}
// do the above for all of the fields, use the data to query database with.
// Perform database operations here
?>
<form action='Page3.php' method='post' name='frm'>
<?php
foreach ($_POST as $a => $b) {
echo "<input type='hidden' name='".$a."' value='".$b."'>";
}
?>
</form>
<!-- Script to submit button -->
<script language="JavaScript">
document.frm.submit();
</script>
I have a very simple app, it's only one php page (page A). I would like add one more php page (page B) that receives data from an html form of "page A". I haven't found any tutorials about it. Can you help me?
GET METHOD
Page A: (eg. index.html)
<form action="welcome.php" method="get">
Name: <input type="text" name="fname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
Page B (welcome php)
Welcome <?php echo $_GET["fname"]; ?>.<br />
You are <?php echo $_GET["age"]; ?> years old!
When to use method="get"?
When using method="get" in HTML forms, all variable names and values are displayed in the URL.
Note: This method should not be used when sending passwords or other sensitive information!
However, because the variables are displayed in the URL, it is possible to bookmark the page. This can be useful in some cases.
Note: The get method is not suitable for very large variable values. It should not be used with values exceeding 2000 characters.
POST METHOD
Page A: (eg. index.html)
<form action="welcome.php" method="post">
Name: <input type="text" name="fname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
Page B (welcome php)
Welcome <?php echo $_POST["fname"]; ?>!<br />
You are <?php echo $_POST["age"]; ?> years old.
When to use method="post"?
Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.
However, because the variables are not displayed in the URL, it is not possible to bookmark the page.
The PHP $_REQUEST Function
The PHP built-in $_REQUEST function contains the contents of both $_GET, $_POST, and $_COOKIE.
The $_REQUEST function can be used to collect form data sent with both the GET and POST methods.
Example
Welcome <?php echo $_REQUEST["fname"]; ?>!<br />
You are <?php echo $_REQUEST["age"]; ?> years old.
If you are using Form on Page A then you can post the values from that form to another page B.
if you are not using post or get you can still pass values from one page to another by creating session.
Html form can have action set to Page B and $_POST or $_GET can give you data from page A to Page B
You are best off looking into a few tutorials this is PHP 101.
You can store the data in a session or cookie.
You can use a form to POST data to the next page.
you can use GET to send data in the uri
Here is a tutorial for POST and GET
Edit : It sounds like you wish to pass the variables with a redirect. You could set the variables in session and retrieve them later or pass the variables in the redirect and fetch them using $_GET. Rather than redirecting to example.php redirect to example.php?var=value.
What I have so far is a paginated page, showing all users in a database system. Each page shows 30 users and has a checkbox next to each user, what I need is a way for users to select and deselect these users and for these selections to propagate through, so if the user goes back to page 1 from page 2, all users from page 1 will still be checked.
I also need a way to record this information, so that once the user has looked at all the pages and clicks a submit form all checked users information can be processed. I am thinking of using javascript to record the information and php sessions to store it, but with the way I am trying now, when a user clicks a checkbox, it is not ticked.
Does anyone have a better way of doing this/see how I can fix this problem?
Thanks.
<script type="text/javascript">
function log_export($str) {
document.check.data.value = $str;
document.check.submit();
}
</script>
<?php
if(isset($_POST['data'])) {
echo $_POST['data'];
}
?>
<form name="check" method = "post" action = "">
<input type="hidden" name="data">
<input type="checkbox" name="A" onclick="log_export('1')" />
<input type="checkbox" name="B" onclick="log_export('2')" />
<input type="checkbox" name="C" onclick="log_export('3')" />
</form>
Few ways you could do this, but I'd avoid using javascript to do it. You could use an array in your $_SESSION to keep the list across pages.
<form name="check" method = "post" action = "">
<input type="checkbox" name="person[A]" />
</form>
(note: The form elements are named person[A], person[B]...etc, so they can be accessed as an array in php and make your life easier.)
Then in the php you can store this in the session...
$_SESSION['saved_list'] = $_REQUEST['person'];
This way the session variable saved_list will contain the array person with all the checked boxes in it. You'll need to be careful not to overwrite the array each time however, so adding...
$_REQUEST['person'] = array_merge($_SESSION['saved_list'], $_REQUEST['person']);
...before this should keep them (if I'm remembering my merge functions correctly).
Alternatively, you could just use html to save the checkboxes already ticked. When page 2 receives the results from page 1, it could print them out as hidden elements at the end of the page 2 form. This way they can exist across pages, however this could become a bit unwieldy with 30 names a page.
I'd suggest storing it in a php session array, this shouldnt really involve using Javascript, it just over-complicates matters.
Why you don't change your form method to GET and make the pagination link so it contains every parameters passed to the form and the page number. I think it make everything more simple to handle that case with parameters passed on the URL against posted one.
you can create those links like this:
for ($i =0; $i < $max_page; $i++){
echo "{$_SERVER['REQUEST_URI']}?$_SERVER['QUERY_STRING']&p={$i}";
and you just have to change your backend to use $_GET instead of $_POST.
