PHP - Posting Form Data

I'm not much of a PHP programmer so please excuse the mess but I'm having a problem with some code. I am able to successfully build a table and assign values to radio buttons based one information in a database. The problem comes when I want to update the database when someone changes a radio button. Everthing works up until the foreach statment. Nothing in the database is being updated, if I replace the sql statement with echo $v; all I get is the word Submit so it's like the rest of the values aren't being included in the form.

So I have an AJAX call that I'm using to POST 1 variable to a PHP script I have on a separate server. The PHP takes this variable and returns data based off of what the variable is. This works on all browsers except IE9 and below. IE9 returns data but it's an error saying the variable is missing which to me shows that it isn't sending the data. Below I have the AJAX call I'm making: (function (jQ) {

var inviteID = '00000000000';

jQ.ajax({
url: 'www.example.com/test.php',
type: 'POST',
dataType: 'json',
cache: false,
data: { classID: inviteID },
error: function (data, status, error) {
jQ('.statusField').append('Failu ' + data + status + error);
},
success: function (data, status, error) {
jQ('.statusField').append('Success: ' + data);
}
});
})(jQuery); And below I have the PHP script that's being used: <?php
//first POST to grab token
function runPost($classID) {

$postdata = array(
'username' => 'username',
'password' => 'password'
);
//open connection
$ch = curl_init();

//set the url, POST data
curl_setopt($ch, CURLOPT_URL, "https://www.example.com/login");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($postdata));
curl_setopt($ch, CURLOPT_USERAGENT, 'example');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

list($message, $time, $token, $userID) = split(',', $result);
list($one, $two, $three, $four, $five) = split('\"', $token);
$four = json_encode($four);
$four = str_replace('"','',$four);


$secondaryPostData = array(
'token' => $four,
'data' => array( 'invitationID' => $classID
));

//open connection
$chu = curl_init();

//set the url, POST data
curl_setopt($chu, CURLOPT_URL, "https://www.example.com/classID");
curl_setopt($chu, CURLOPT_POST, 1);
curl_setopt($chu, CURLOPT_POSTFIELDS, json_encode($secondaryPostData));
curl_setopt($chu, CURLOPT_USERAGENT, 'example');
curl_setopt($chu, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($chu, CURLOPT_RETURNTRANSFER, 1);

//execute post

$secondResult = curl_exec($chu);

//close connection
curl_close($chu);
return json_encode($secondResult);
}
//Grab classID from javascript
echo runPost(trim($_POST['classID']));
?>     Again, this works fine in everything except IE. I've tried using just $.post and even XDomainRequest() and get the same result. The network console in IE shows that the Request body does have the classID in it, but I'm guessing it's just not sending the data to the PHP script. I don't know if I'm missing something that IE needs to send this to the PHP script but any help with this would be GREATLY appreciated.

I'm trying to figure out a way to post data directly to a URL. For example:



<?php 
if (isset($_POST["pass"]) && ($_POST["pass"]=="$password")) {

echo "You did it";

?>

<?php 
}
else
{
  echo "<form method=\"post\"><p align=\"left\">";
  echo "<input name=\"pass\" type=\"text\" size=\"25\" maxlength=\"40\"><input value=\"Enter Pass\" type=\"submit\"></form>";
 exit;
} 
?>


Let's assume $password is 'password'. Why can't I simply pass the information through the URL to access the page with something like this:

Code: [Select]
http://mypage.com/the-same-page.php?pass=password

Hi,   I have a database which holds results     Name | Car | etc \ etc | Round 1  |  round 2   | round 3 // etc  | Total   the points are in the format of; e.g. 100.5  // 25.6  // 35.8  // 50.0   I input the data manually using a webpage, clicking on the relevant driver, update scores, click submit.  I have to manually work out the total, is there a way I can it it automatically add the values from round 1,2,3, etc.

Hello.  I currently have a web page that allows a user to enter text into a form then select a "Submit Query" button; upon doing this the entered text is saved to a database and displayed for the user on the same page (the page where the form and "Submit Query" button are located).

My question is as follows: I wish the results to be displayed on a new page when the "Submit Query" button is clicked, not displayed on the same page.  Is this achieved through targeting? I am a bit lost at this point on how to achieve this result.

Thank-you in advance for any help.

I am working on a PHP/MySQL authorization script.
The script seems to work initially, but when I try to Login and post the Form (
        echo '<form method="post" action=authorize_1.php">';
   echo '<table>';
   echo '<tr><td>Userid:</td>';
   echo '<td><input type="text" name="userid"></td></tr>';
   echo '<tr><td>Password:</td>';
   echo '<td><input type="password" name="password"></td></tr>';
   echo '<tr><td colspan="2" align="center">';
   echo '<input type="submit" value="Log in"></td></tr>';
   echo '</table></form>';
)
Internet Explorer returns the error that the page is not found.... but I am using one .php file for the authorization so I am sure the page is found because i can see the Login portion.

Any ideas as to what is going wrong?

I have this code with clears the input box onclick...
Code: [Select]
<input type="text" name="username" value="Username" onclick="value=''"/>

however is there any way to use php to get the value of username, before its posted?

that way i can make it so it only clears if the value of username is "username"

Hi, i have written a form that uses 3 dropdown boxes, one of them being populated from a database.

The form code is as follows;

Code: [Select]
<form id="pointsForm" name="pointsForm" method="post" action="points-engine.php">

<select name="car" id="car">
<?php
        // result of car name collection
        $result = mysql_query ($query);
        
        //Array stored in $cars
        while($cars=mysql_fetch_array($result)){
            
        //option values added by looping through array
        echo "<option value=$cars[id]>$cars[carName]</option>";
        }
?>
</select>

<select name="season" id="season">
<option value="low">Low season</option>
<option value="mid">Mid season</option>
<option value="high">High season</option>
    <option value="peak">Peak season</option>
</select>
   
    <select name="period" id="period">
<option value="day">One day</option>
<option value="weekend">Weekend</option>
<option value="week">One week</option>
</select>

<input type="submit" name="Submit" value="Submit" /> 

</form>
which posts to;

Code: [Select]
<?php

$car=$_POST['car'];
echo $car;

$season=$_POST['season']; 
echo $season;

$period=$_POST['period'];
echo $period;

?>
The initial form code is working fine, the car field is being populated from the database. My problem is the post value for car isn't working...

points-engine.php is echoing $season & $period fine but not $car

can anyone tell me why?

many thanks
Richard

Hi Guys,

I need a bit of help. I need to post a value to a second page, but I want the button to have the same name.

The page is to show registered users and then allows a user to send a friend request 'to put it in simple terms'.

Username submitbutton username submitbutton And then i do the following

<?php
foreach ($_POST['username') as $user
{
echo $user;
}
?>
How could i go about doing this or would I have to use a 'Hidden' Field.

Hi There,

I have a series of submit buttons that I would like to update records in a table when they are pressed. For example, when clicked, I would like them to run the following statement:

update mytable set completed = 1 where colname = $variable

I would then like it to refresh the page.

Is there a way of doing this?

Thanks
Matt

Hi, I got this form which passes hidden values as well as a select menu.  The only thing is, it doesnt seem to post the form data to the script.   Here is the form

echo '<form action="regsale.php" method="POST">';
echo '<input type="hidden" name="username" value="<?php echo $username ?>"';
echo '<input type="hidden" name="listing_title" value="<?php echo $listing_title ?>"';
echo '<input type="hidden" name="speciesCommon" value="<?php echo $speciesCommon ?>"';
echo '<input type="hidden" name="cost" value="<?php echo $cost ?>"';
echo '<input type="hidden" name="business" value="<?php echo $business ?>"';
echo '<input type="hidden" name="postage_cost" value="<?php echo $postage_cost ?>"';
echo '<input type="hidden" name="multipostage" value="<?php echo $multipostage ?>"';

echo "<ul class='results'>";
echo '<li>Quantity:</li>';      
echo '<select name="quantity">';
echo "<option value='$quantity'>Maximum of $quantity available</option>";
for ($q=1; $q<=$quantity; $q++) 
{
    echo "<option value='$q'>$q</option>";
}
echo '</select>';
echo' </ul><br>';



echo '<div align="center">';

echo '<input type="submit" value="Confirm Purchase"><br>';

<h1>Payment to <?php echo $username ?></h1><br> works, but I think that is because it is passed in the SESSION.   Any other $variable such as those below

echo '<strong>Thank you for confirming you would like to purchase $speciesCommon; </strong>';
echo '<br>';
echo '<strong>Your payment comes to a total of $total; </strong></h2>';

does not work.   Why is the form not posting the values to the database.   Just in case it helps, the form gets its values from the database, and the values are displayed in the sales page on which the form is contained. Here is the page containing the form.
