PHP - Posting An Array Problems

I am trying my hand at using an array i have never done it before, and I am having some problems getting it work work. if someone could point me in the right direction?

Thanks



<?php

$active_keys = array();
foreach($_GET['img'] as $key => $filename)
{
    if(!empty($filename))
    {
        $active_keys[] = $key;
    }
}



?>

i have a users online section and i am using an aray and implode so the comma is displayed on every username but the last, but it displays the same usernames several times. This could be due to the switch i am using to define user group. Heres the code:

$online_query = $db->query("SELECT user_id, user_group, user_username
                            FROM ".DB_PREFIX."sessions");
while ($online_info = mysql_fetch_object($online_query)) {

switch($online_info->user_group)
        {
            case 1:
                $userClass = 'admin';
                break;
            case 2:
                $userClass = 'mod';
                break;
            case 3:
            case 0:
            default:
                $userClass = 'user';
                break;
        }

$users2[] = "<span class=\"{$userClass}\">{$online_info->user_username}</span>"; 

echo '<p>' . implode(', ', $users2) . '</p>';
}

is there something i am doing wrong?

Having problem with a bit of code.   I am trying to fetch data from the database, I have used mysql_fetch_array before, and even in later bits of code.  I want to use this data for an IF statement later on.  The IF statement isn't there, because this code is catching somewhere.  The fetch array is working fine, and it echos out the correct row in database that it should.  The issue, it stops displaying code that follows it.   

In the code, I have put a comment (// Code kills here ....) where the code is killing.  I have identified the few lines of code that is killing the script.

You can see the page.. The number 71 is what is supposed to be supplied by the query and array.  This is the page as it is with the trouble code. 



Here is the page without the trouble bit of code, and it displays all that it should.  But it doesn't have the functionality I want to build in with the array obviously.




Here is the code with highlight bit of trouble:

/source/userinfo.php
Code: [Select]
<?php
include ("db.php");


$get_info = mysql_query ("SELECT * FROM registrations WHERE u_id=$uid AND appid=$appid" , $link2);

//Begin Trouble Code

while ($check = mysql_fetch_array($get_info))
{

echo $check['assign_id'];

}

//End Trouble Code

// Code kills here, for some reason....  Proper assign_id displayed, but it kills script.




$count = mysql_num_rows($get_info);


if ($count >= 1)

{

$get_jos_info = mysql_query ("SELECT * FROM jos_users WHERE id=$appid" , $link);

$get_avatar = mysql_query ("SELECT * FROM jos_comprofiler WHERE user_id=$appid" , $link);


while ($avatar_link = mysql_fetch_array($get_avatar))

$avatarurl = $avatar_link['avatar'];

echo $avatar_link['avatar'];
echo "<table border='0' width='70%' align='center' cellpadding=5>";
 
while ($rowteam = mysql_fetch_array($get_info))
{

echo "<tr><td width=40% align=right><strong>Age</strong></td><td width=60% align=center>$rowteam[age]</td></tr>";

I included this bit of code so you can see some of the variables that were assigned in another file.

I'd like some help debuging my code, I can't seem to figure out why it isn't creating the variables... Here it is:


<?php
$template_settings = array(
"index"=>"index.php",
"announcements"=>"announcements.php"
);

extract($template_settings, EXTR_PREFIX_ALL, "template_");
echo $template_index;
?>


No matter what I do $template_index still equals null and I'm wondering what I'm doing wrong. There are no errors of anykind.

The code here is suppose to allow the user to match up a word ($word) with a list of definitions ($word_defs).  I can't get the list of definitions to stick.  When the user does make a guess it shows that he is always correct.  How can i fix these problems?

 Outside entry code:
Code: [Select]
<?php
require_once "include/session.php";
require_once "include/word_defs.php";
 
$word = array_keys($word_defs); 
$word_defs = array_unique(array_values($word_defs));

$params = (object) $_REQUEST;
$session = new Session();
 
if (isset($params->guess)) {
  $word = $params->word;
  if ( $params->word == $word_defs[$term] ) {
    $response = "correct"; 
  } else {
    $response = "incorrect"; 
  }
  $choices->word_def[$params->word_def] = "selected";
} else {
  $word = $word[ rand( 0, count($word)-1 ) ];
}
?>

Body code:

Code: [Select]
word: <?php echo $word ?>


<form action="?" method="get">
definition:
<select name="word_defs">
<?php foreach ($word_defs as $word_def): ?>
<option <?php echo $choices->word_def[$word_def] ?> ><?php echo $word_def?></option>
<?php endforeach ?>
</select>
 
<input type="submit" name="guess" value="Guess" />
 
<input type="hidden" name="word" value="<?php echo $word?>" />
</form>

<h3><?php echo $response ?></h3>

Problem: my checkbox array chkBrand[] is not saving data when I click the save button called cmdSave. Each checkbox specifies a brand connected to a model number. Multiple brands can be connected to each model number. (Don't ask, it's what the customer wants.)

So, if I check the checkbox in row 0 and row 3, only row 0 shows up. If I check the boxes in row 0, 1, 5, only rows 0, 1 show up in chkBrand and $newchkbrandarr.

First, my routine to see which button is checked is at the top of the php file. Here it is.

else if (isset($_POST['cmdSave'])) //Try to save items first.
    {
$newchkbrandarr=$_POST['chkBrand']; //Checkbox for each brand.
$oldchkbrandarr=$_SESSION['oldchkbrandarr'];
$olddata=$_SESSION['olddata']; //Non-brand Fields strung together.
$brandlist=$_SESSION['brandlist']; //List of brands displayed.

crPrintarr('chkBrand raw',$_POST['chkBrand']); //DEBUG. Prints array to screen.
//===At this point chkBrand[] contains: 1

//Turn nulls in checkboxes to zeros.
$cnt=count($newchkbrandarr);
for ($j=0; $j<$cnt; $j++)
{
$newchkbrandarr[$j]=$newchkbrandarr[$j]+0;
} //for j

//Make sure that at least one brand is checked.
$cnt=count($newchkbrandarr);
crPrintarr('newchkbrandarr',$newchkbrandarr); //DEBUG
//===At this point, $newchkbrandarr contains: 1, 0

$s='Elements in newchkbrandarr cnt='.$cnt;
$s.=', count brandlist='.count($brandlist);
crDebug($s); //DEBUG
$cnt2=0;
$cnt=count($newchkbrandarr); //Find number of elements.
for ($j=0; $j<$cnt; $j++)
{
$cnt2=$cnt2+$newchkbrandarr[$j]+0;
//$s='arrpos '.$j.': newchkbrandarr='.($newchkbrandarr[$j]+0).', cnt2='.$cnt2;
//crDebug($s); //DEBUG
} # for j


Here is my code to construct the array of checkboxes, one per table row. Each checkbox has its array position explicitly defined as $x. $x starts at zero, and is incremented by 1 for each table row (each check box).


    $x=0;
    while ($row = mysqli_fetch_array($result)) 
     {
$br=trim($row['brand']); //Brand name to display
$brandvar=$br;
$brandlist[]=$br; //Save every found brand for later.
//First find if brand is checked on table "brands". 
        $query2 = "SELECT brand ".
        "FROM brands ".
        "WHERE ".
        "(partid=".$partidvar.") ".
        "AND (brand='".$br."') ".
        "ORDER BY brand ".
        ";";
        $cntchk=crqryCount($query2,false); //If $cntchk>0 then brand is checked.
        //$s="Is brand stored already? <br/>$query2";
        //crDebug($s); //DEBUG
        
        $query2 = "SELECT brand ".
        "FROM zzbrands ".
        "WHERE (brand='".$br."') ".
        "AND (prodnameoverride=1) ".
        "ORDER BY brand ".
        ";";
$override=crqryCount($query2,false); //Can this brand override product name?

$s="\n";
     $s.='<tr><td>'.
         '<input type="text" value="'.$br.'" id="txtBrand[]" name="txtBrand[]" '.
         'size="20" readonly class="mydisabled" />';
     $s.='<td align="center">';
     $s.='<input type="checkbox" name="chkBrand['.$x.']" '.
         'id="chkBrand['.$x.']" value="1" ';
     if ($cntchk>0)
     {
     $s.='checked="checked" ';
     $oldchkbrandarr[$x]=1;
     }
     else {
     $oldchkbrandarr[$x]=0;
     }
     $s.='/>';


Any ideas what I might be missing?

Hi All,   I'm new to PHP (not to coding) - and I've been able to bang out most answers using books, the web and brue force - but this one has me stumped. (If it's been covered before, sorry, I'm being lazy for not searching)...   So, here's the problem:   I have a call to my internal system that returns XML data via a SOAP call. The call works great - data is returned as I would expect.   Like I've read, I put said data into a variable usng simpleXML like this: $xml = simplexml_load_string($response3); ($response3 being where the raw data is)   When I do a var_dump of $xml, I get this:   SimpleXMLElement Object
(
    [ICProductAvailByWhseResult] => SimpleXMLElement Object
        (
            [errorMessage] => SimpleXMLElement Object
                (
                )

            [arrayAvailability] => SimpleXMLElement Object
                (
                    [ICProductAvailByWhse.output.Availability] => Array
                        (
                            [0] => SimpleXMLElement Object
                                (
                                    [productCode] => xxx       
                                    [description1] => yyy          
                                    [description2] => zzz
                                    [warehouse] => aaa
                                    [netAvailable] => bbb
                                )

                            [1] => SimpleXMLElement Object
                                (
                                    [productCode] => xxx
                                    [description1] => yyy          
                                    [description2] => zzz
                                    [warehouse] => aaa
                                    [netAvailable] => bbb
                                )

                            [2] => SimpleXMLElement Object
                                (
                                    [productCode] => xxx
                                    [description1] => yyy          
                                    [description2] => zzz
                                    [warehouse] => aaa
                                    [netAvailable] => bbb
                                )
  **** Edited, I got real data, not xxx,yyy, etc... ****   Now the issue:  It seems like I have everything in place - all I need now is to get my data off to variables for display. I've tried everything I can think of and I just can't seem to get it.   I ran $xml->getName() and it gave me: ICProductAvailByWhseResult   So, simple I think, I should be able to print something like $xml->ICProductAvailByWhseResult[0]->warehouse and I should get something, right? Nope.   So I try $xml->ICProductAvailByWhseResult[1]->warehouse and I get a notice that I'm trying to get to a property of a non-object.   What am I missing?  I come from a VB backgound, so I understand array's and such - but this one has be stumped.   And help would be greatly appreciated...   Thanks!!  

I have a text field in my database that I'm pulling the contents of and parsing into an array, at which point depending on the users action I'm either adding to the end or searching for a specific value and removing it.  I'm then converting the array back to a string and placing it back into the text field in the database.

Everything works fine except for either an empty array value or a new line forcing its way to the front. Causing, naturally an empty value loaded onto the page that displays this part of the db.

While I know theres a couple things in there that aren't necessary I was just too lazy to take them out before posting after attempting to find a way around this problem. But here is the bulk of the code.  I appreciate any help!

$to_add = "SELECT * FROM teams WHERE name = '$teamname'";
$que_to_add = mysql_query($to_add);
while ($fetch_members = mysql_fetch_array($que_to_add, MYSQL_BOTH)) {
$members = explode("\n", $fetch_members['members']);
$members = array_filter($members);
foreach ($members as $key => $value) {
$value = trim($value);
$new_insert[] = $value;
}
}
$new_insert = array_filter($new_insert);
foreach ($new_insert as $key => $value) {
if ($value != "") {
$to_insert = ($to_insert . "\n" . $value);
}
}
$to_insert = ($to_insert . "\n" . $for_insert);
$insert_ready = "UPDATE teams SET members = '$to_insert' WHERE name = '$teamname'";
$insert = mysql_query($insert_ready);

i'm doing a form that posts values to XML, and i don't know how.

can someone help me with a quick lesson in passing variables/XML data? i don't even know what question to ask, actually -

the XML format i've been given is:
Code: [Select]

<?xml version="1.0" encoding="UTF-8"?>
<lead>
    <innerNode></innerNode>
    <last_name>Smith</last_name>
    <first_name>John</first_name>
</lead>


and what i've come up with so far is this, but i don't even know if i'm on the right track:

Code: [Select]


$last_name = $_REQUEST['l_name'];
$first_name = $_REQUEST['f_name'];


$url = "http://url.com/leads";

$post_string = '<?xml version="1.0" encoding="UTF-8"?>
<lead>
    <innerNode></innerNode>
    <last_name>'.$last_name.'</last_name>
    <first_name>'.$first_name.'</first_name>
</lead>';


$header  = "POST HTTP/1.0 \r\n";
$header .= "Content-type: text/xml \r\n";
$header .= "Content-length: ".strlen($post_string)." \r\n";
$header .= "Content-transfer-encoding: text \r\n";
$header .= "Connection: close \r\n\r\n";
$header = $post_string;

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

$data = curl_exec($ch);

if(curl_errno($ch)) {
    print curl_error($ch);
} else {
echo "yay";
    curl_close($ch);
}

i'm being told "should return a response.xml with either a success or failure post status." which is confusing me

can someone help a bit?

thanks very much...

hello, i have a while loop that displays multiple tables of data depending on how many are in the database... i have a link if you click it will redirect to another page that prompts you to save an xls file with the table data... this was all working for me before when i had the while loop display rows of data in one table...well i decided that i would like the while loop to display a separate table each time... when i changed it... the xls file only shows one table of data... how can i set up so it will export all tables of data... is there some kind of loop i can set up for it to append the tables??

i have the table data all in a variable $table which i put into a hidden form field that redirects to the xls export page.... any help is appreciated...
