PHP - Can't Pass Variables To A Page

I am trying to build a website, whe   1) User logs in (UserA) 2) Inserting a name in the search box and pressing "Search", a list of all users matching that name is shown 3) The user selects a user (UserB) from that list (among several results) 4) By selecting the user (UserB) , a message box appears to insert text 5) The user(UserA) types the message 6) The user(UserA) presses the SUBMIT button and sends the message to the other user(UserB)   The problem i face is how to pass the variables from my PHP script to the JavaScript script. Its easy for me to get the values of input fiedls, select fields or any other DOM element value. But if the value i need to pass to Javascript file to perform an AJAX call isnt inside a DOM element, how do i do it?   For example, for me to determine the user that will send the message (userA), i will need several data. This data, i have them inside the PHP script as variables, but dont know how to pass them to Javascript file.   Getting the data from the URL, or from a hidden input field or any other DOM element, is a solution, but i want to know the way that is safer and better.   To summarize:   [PHP Script with necessary data]-->[pass necessary data from PHP to JavaScript file]-->[perform an AJAX call] --> [return data to PHP Script]   How do i do it?   Thanks in advance.

I have a form, where I'm collecting registration info - like name, address, email, password. I'm calling another php file at server side code, where it will check whether the email exists or not. Pretty simple, just receiving those post variables and check with the database.

The issue, if I find a match, I want to go back to the registration.php page, using the following code:

if ($email_already_use == "y") {
      $_SESSION['ERROR'] = "Error";
      $_SESSION['MESSAGE'] = "This email address already used. Please try another";
      header("location: ".$settings['site_url']."registration.php");
      exit;
}

Now, I would like to place the user input at the registration.php file, but I do not want to use pass variable at URL like this:

header("location: ".$settings['site_url']."registration.php?".name=$name&address=$address&email=$email;

Is there anyway, I can retrieve those variables at registration.php, without specifying .name=$name&address=$address&email=$email ?

Thanks for your help. I see some sites has similar implementation, but did not find anything like how to do it.

Hello everyone,

Can someone show me a way how to pass $_post variable from a form to a function?

So, input username and input password to a function login($username, $password).

Hello,

I am new to PHP and would like to know what I am doing incorrectly.  I have designed a login form which contains two variables: the username and the password.

So for the username:

<input type="hidden" name="email" id="email" value="example_username">

And for the password:

<input type="password" name="password" id="password" size="15">

I then created a php script which I want to pass the variables "email" and "password" to the e-mail address:
 
 
<?php



{

   $message = "$email";

   $message2 = "$password";

   mail ("email@myserver.com", "Hello", $message, $message2);



}

?>


This should happen through the command:

<action="http://www.myserver.com/myscript.php" method="post">

All I get is a blank email with the subject "Hello".  Why are the email and password variables not being passed to my email by the php script?

Thanks.

I have a search page that then submits to a php page that queries the database. I've been struggling to figure out how to paginate it, but I think I've narrowed down the problem. I didn't realize $_POST results didn't pass through when people clicked the pagination links at the bottom. I verified this by replacing  the LIKE variable with a specific word and it worked.

I'm trying to learn how to set up sessions, thinking this might solve my problem. Doesn't seem to be working. Can I get some suggestions on how to do this? What's happening now is that it's pulling a random 8 pages that have nothing to do with the original query.

I start my entire page with:
Code: [Select]
<?php

session_start();

$_SESSION['leafshape'] = $_post['select1'];
$_SESSION['leafcolor'] = $_post['select2'];
$_SESSION['leafvein'] = $_post['select3'];
$_SESSION['leafmargin'] = $_post['select4'];

$leafshape = $_SESSION['leafshape']; 
$leafcolor = $_SESSION['leafcolor'];
$leafvein = $_SESSION['leafvein']; 
$leafmargin = $_SESSION['leafmargin']; 

and I'm setting up the queries like this:
Code: [Select]
$query = "SELECT COUNT(*) as num
                    FROM
                        descriptors
                    JOIN
                        plantae ON (descriptors.plant_id = plantae.plant_name)
                    WHERE
                        descriptors.leaf_shape LIKE '{$_SESSION['leafshape']}'
                        AND descriptors.leaf_venation LIKE '{$_SESSION['leafvein']}'
                        AND descriptors.leaf_margin LIKE '{$_SESSION['leafmargin']}'";

I also tried replacing the '{$_SESSION['leafshape']}' in the query with the assigned variable $leafshape

Before, if I wanted to send a welcome letter when a user registers i'd do this.

$body = "<inserted html code>";
mail('email@email.com', 'Subject', $body, $headers);


Now that I am advancing in PHP, I was trying a different method, because when I did the above method, I would have to take all the HTML out of the variable to change something, like an image link, etc...

I have tried doing another method, where I can actually leave all the HTML code in a separate file, so that I can easily edit it, and tried 3 things...

This one works, but it doesn't pass variables:

$body = file_get_contents("emailTemplate.inc.php");
mail('email@email.com', 'Subject', $body, $headers);

When I do this one, the page actually just shows on the current page (naturally):

$body = include("emailTemplate.inc.php");
mail('email@email.com', 'Subject', $body, $headers);

Of course, this has the same effect as the include function:

$body = require("emailTemplate.inc.php");
mail('email@email.com', 'Subject', $body, $headers);

So my question is, how do I send a formatted HTML email, and pass variables to it, so I can personalize it by the persons name, etc, without adding the HTML to a variable, and so that I can easily update the page whenever I want, and without taking it out of the variable, and sticking back in the edited code?

Any help would be appreciated! I would also like to say that I am using this code for the $headers variable too:


$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: from@email.com <email@email.com>' . "\r\n";

Thank you in advanced!

I have the array defined and print_r (outside the function is show what I need...)
However, I need to somewhay pass those three arguments - name, price, shipping (keys & values) into the "all_products" function and assign (inside the function) each element to a variable {name, price, shipping}.

Code: [Select]
function all_products($key,$value) {

# This is where I'm lost - I know the values are passed to the function but how to I assign them to below variable?
echo "$name";
echo "$price";
echo "$shipping";


// Products array defined to send values into "all_products" function & loop to display item name & individual pricing (using WHILE LOOP)
$products = array('Product1' =>
                                    array   (   'name'  =>  'item one',
                                                'price' => '30.00',
                            'shipping' => '0.00'),
             'Product2' =>                       
                        array (   'item two',
                                                'price' => '19.50',
                            'shipping' => '0.10'),
             'Product3' =>
                        array (   'item three',
                                                'price' => '21.99',
                            'shipping' => '0.10')
                                                );


while (list($keys, $values) = each($products)) {
             while (list($k, $v) = each($values))
   echo "Checking Looped Data Outside Function: <strong>$k: </strong> $v<br/>";

#   echo "<pre>";
#   print_r($value);
#   echo "</pre>";

# Trying to send array elements into "all_products" function & echo (name, price, shipping) keys and values inside that function
all_products($k,$v);

}

i knw dis mst a simple question but how to pass variable to other page
for eg i hav created a page where user submits username n telephone then via sms some random number goes to user mobile ...i want this random number variable in other page
 dis is my code for startreg.php

<form action="startregprocess.php" method="post">
username:<input type="text" name="username">
telephone<input type="text" name="telephone"
<input type="submit" name="submit">
</form>
<?php
srand ((double) microtime( )*1000000);
$random_number = rand( );
echo $random_number;
?>


i want tht $random_number in other page called startregprocess.php

I have a page that has roughly 100 text input fields.  Once the user is done, I need to put the data in my mysql db.  How do I get the data from the user input page to the php page that will process the data (e.g. process.php)?

I've done some searching and found a few possibilities use a ajax style call back to load a seperate asp page (e.g. createsession.asp) and that page set session variables that can then be read by process.php write everything to a cookie using some sort of a delimiter so that it can handle multiple variables (e.g. cookie data => var1/var2/var3/var4... write all the data to a text file and then have process.php load that file
Which should I pursue?  Is there a better option?

I have this function where i want to pass the month and year according to the date drop down that is chosen by the user. But can't seem to get the selected month and year. But instead, i got the month and year for now (which is April 2020). Can any one show me how can i achive this? I mean how can i pass the month and year selected to my `allreport-summary.php` page. It would be better if you guys can show me examples of codes on how can i implement this. Any help will be appreciated. Thank you so much. cheers!

Hi guys,

I know that you can open web page with $handle = fopen("http://www.example.com/", "r");
but i am wondering is there a way to pass POST vars when doing so, or there is another method that can that like you do it with ajax.

I have mvc application that i want to test. I am using CodeIgniter framework so i want to call my controllers
with POST values. Every controller method returns data holder object that holds the data of operation whether is successful or not. Also every method inside controller can be called with parameter input or with post input. If you omit the parameters when calling controller method than he will try to load that parameters from post and that is why i want to pass POST vars with php when calling controller for example i want to call:

fopen("http://localhost/MyAppFolder/index.php/controller/method");

but i want to pass it some POST vars if that is possible

Thanks.
