I just want to know how will i pass a session variable frm php to html thru js and from there to the php page where action of the html page occurs?

Ok here is what im trying to do:
1. drop down list pulled from mysql database.( working )
2. after you select the name in the drop down list
3. Use selected name to another page.
here is code


Code: [Select]
<?php
include('include/db_connection.inc');

$table = "truck_master";

$result = mysql_query( "SELECT driver_name FROM $table" );

$options=""; 
while ($row=mysql_fetch_array($result)) {

$driver_name=$row["driver_name"];

$options.="<OPTION VALUE=\"driver_name\">".$driver_name.'</option>';




} ?>
<html>
<head>
</head>
<body>
<table align="center">

<form name="form1" method="GET" align="center" action="issue.php">

<tr>
<td>Driver Name :</td>
<td><SELECT name="driver_name"><OPTION VALUE=''>Choose<?php echo $options?></SELECT> </td>
</tr>
<tr>
<td><input type="submit" name="Submit" value="Submit"> </td>
</tr>
</form>
</table>
</body>
<html>
Second Code IS
Code: [Select]
$driver = $_GET['driver_name'];

So, I have a checkbox, like so:

(uci is an ID number)
<input type='checkbox' name='cars[]' value='".$row['uci']."' />

That is passed to the next page via the form. However I need to pass the id numbers again, through to a third and final page. Currently I'm trying to do it through hidden inputs, but all I get returned to me is the word, "Array".

This is the second page, displaying the data it recieves from the checkbox on the first page and attempting to send it through to the third page via a hidden input.

$ids = $_POST['cars'];

...
Displays data here...
...

<form action='step_3.php' method='POST'>
<input type='hidden' name='cars' value='$ids' />
<input type='submit' name='submit' value='Final Step' />
</form>


I also tried <input type='hidden' name='cars' value='".$_POST['cars']."' /> but that didn't work either.

This is what I'm using to display the data on the final page, as a check to make sure it's working (this is where I'm just getting the word, "Array"):

echo"Car Id's: ".$_POST['cars']."<br />";

So, I guess my question is how do I pass the multiple options checked on the first page through more than one page? It works fine displaying the data on the second page, however when I try to display it again on the third page via the hidden input, it doesn't work.

Hi all

Basically, I have a form which when done will calculate a quote for turf for given areas. Basically each time the user specifies an area it goes into an array, and they can add as many as they want, but the problem seems to be once submitted and it arrives back into the program, it isn't decoding so the multidimensional array is lost. What am I doing wrong here?

Full code below, thanks in advance

Code: [Select]
<?php // Framework

// Get the sections
$sections_array = base64_decode(unserialize($_POST['sections']));

// Build the rest of the array
foreach ($sections_array as $section) {

$sections[] = base64_decode(unserialize($section));
}

// Set the initial unit
$units = $_POST['units'];

// Do the new add
if ($_POST['a'] == 'add_section') {

// Add the new measure
if ((is_numeric($_POST['width'])) && (is_numeric($_POST['length']))) {

$sections[] = array('length' => $_POST['length'],
    'width' => $_POST['width']);
}

$sections_array = base64_encode(serialize($section));

Hi

I struggle with something i'm trying to achieve. Maybe this is not the correct approach, i don't know.

My goal is to attribute a string of a field of the form to a string variable in order to use this string variable in order to "auto fill" the field of the form previously completed.
This is to do what is apparently called a sticky form...

First the program attributes the string of a field of the form to a string variable :

$EmitterFirstName = $_POST["EmitterFirstName"];


Then in the html form there is a field called "EmitterFirstName", and i want to use the string variable $EmitterFirstName in order to auto fill the field with the string previously typed by the user :

<input type="text" name="EmitterFirstName" value="<?php $EmitterFirstName ?>"/>


But it doesn't work as expected. Do you have any idea why or maybe an advice on how to code such a thing ?

Thanks,

Code: [Select]
<form action='test.php' method='post'>
<input id="Username" type="hidden" name="date2" />
<input type="submit" name="action" value="Submit"></form>

Hi I want to pass a Username javascript variable to test.php as hidden, anyone can help?

When code this
Code: [Select]
<input id="Username" type="input" name="date2" />Data can pass to test.php

When code this
Code: [Select]
<input id="Username" type="hidden" name="date2" />Data fail to pass over

How, if possible, can a $var  be passed to the  forms action php file?

I tried everything with no success.

Trying to set up an error message when someone tries to upload a file without the approved .ext.
I have it working so it won't up load but I am trying to get an error to print out.

I was thinking that I could do something like this

if the ext are wrong set
$errorMsg1 == 1;
and then the page will refresh and I would pass that variable to echo out

if ($errorMsg1 == 1){
echo "Invalid"; }
else {

but it isn't passing can anyone help me with this? Tyring to keep it simple

this is the code to select an image

else{
 
  $result = mysql_query("SELECT * FROM photos WHERE userID LIKE '$clientID'");
  while ($r=mysql_fetch_array($result))
  {
     $photo_1=$r['photo_1'];
     $photo_2=$r['photo_2'];
     $photo_3=$r['photo_3'];
     $photo_4=$r['photo_4'];
     $photo_5=$r['photo_5'];

   echo " 
    <form enctype='multipart/form-data' action='' method='POST'>
      <input type='hidden' name='MAX_FILE_SIZE' value='500000' />
      <div id='imageTop'>Image &#38;#35;1</div>
        ";
        if ($errorMsg1 == 1){
       echo "Invalid"; }
       echo "

           if (empty($photo_1)) {

    $NewPhotoName = $finalName; 
    $withExt = $NewPhotoName . $extension;
    $filename = $save_path . $NewPhotoName . $extension; 
    if(move_uploaded_file($_FILES['photo_1']['tmp_name'], $filename)) {

hello all,

I'm new here and I'm learning mysql/php.  Currently I have a dynamic table on one of my webpages, and the loop code looks like this:while ($i < $numRows) {
$fname = mysql_result($result, $i, "fname");
$fcode = mysql_result($result, $i, "fcode");
$ftype = mysql_result($result, $i, "ftype");
$fdesc = mysql_result($result, $i, "fdesc"); ?>
  <tr>
<td><a href="showfunction.php?fname=<?php echo "$fname"; ?>" target="_self"> <?php echo "$fname"; ?></a></td>
<td> <?php echo "$fdesc"; ?> </td>
<td><div align="center"> <?php echo "$ftype"; ?> </div></td>
  </tr>
<?php $i++; 
  } ?>
what I would like to do is pass the ''fname'' variable to the "showfunction" page so it can printed from the database.  Here is the relevant portion of the page:<body><div class="codeblock"> 
<div class="title">Code:<br /> 
</div><code><pre>

<?php echo $fcode; ?>

</pre></code></div>

I know that doesn't work, and I didn't expect it to because there is no way to 'get' the 'fname' variable from the preceeding script.  I do not want to use the GET method with this because from what I understand, you can only use it with Forms.  I really don't want to put controls in all of my table fields just to be able to pass the function name to the next page.  Does that make sense?

If I could get a jumpstart on this one last hurdle, I would appreciate it.  thank you so much!

Cheers.

Hi, can anybody please tell me how i can make "Arson" into a php variable

Code: [Select]

<script type="text/javascript" src="js/swfobject.js"></script>
<script type="text/javascript">

swfobject.embedSWF(
  "open-flash-chart.swf", "my_chart",
  "550", "400", "9.0.0", "expressInstall.swf",
  {"data-file":"ofc-chart.php?crime=Arson"} );
 
</script>
 

This is driving me MAD!

The Variable gets passed through the URL but when I try and echo the result I gte NOTHING.

First Page.

Code: [Select]
<?php include'config.php';


$result = mysql_query("SELECT * FROM carbontrust");

while($entry = mysql_fetch_array($result))


Print "$entry[contact] - $entry[company] :: <a href='edit.php?id=$entry[id]'>Edit</a><br>";

exit;

?>


Second Page. (Where I want the Variable passed to)
Code: [Select]
<?php include'config.php';


$id = $_GET['id'];
echo "ID: $id";


}


?>

Its probably just a stupid error but iv looked through a load of tutorials and this should be correct. :/

Hi,

<?php
} while ($row_subcats_RS = mysql_fetch_assoc($subcats_RS));$rows = mysql_num_rows($subcats_RS);
  if($rows > 0) {
      mysql_data_seek($subcats_RS, 0);
  $row_subcats_RS = mysql_fetch_assoc($subcats_RS);
  }

</select>
</form>How can I pass the variable in the URL?
Thanks

I'm an hour worth of searches into this. It's 2:30. I just want some nice person to give me the answer.

I'm trying to pass a variable using href to another page. It works great if the variable is only one word. But it only passes the first word. There are multiple posts on this topic, but I can't seem to get any of those fixes to work for me.

Here the code.
Code: [Select]
<?php
$query = "select DISTINCT city from daily where open_bid>0 order by city ASC";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$details='';
$details.='<li class="menu"><span class="name"><a href=list.php?city='.$row['city'].'>'.$row['city'].'</a>';
$details.='</li>';
echo($details);
}
?>

As you can imagine, some cities names are made up of two words. This is only passing the first word.

Thanks for your help.
