PHP - How To Assign A Variable The Value Of A Mathematical If Statement?

Hello All,

I have two php files original.php and return.php
retrun.php file returns a variable after I pass $channel_name to it
Code: [Select]
return $return_variable;
I want to assign this return variable to a variable in original.php
Something like this
Code: [Select]
$results =  include ('return.php?channel='.$channel_name.'');I am not sure how to do the above code. When I call the return.php from a  browser it works properly.

Thanks for any help

I get the following error when I try to pass a value to a methiod in a loop:

Warning: Attempt to assign property of non-object in /Users/staceyschaller/Sites/dev_zone/ckwv2/classes/class.php on line 670

This one has me very baffled. It will work the first time, and seems to work every other time, so I have no clue what is wrong. Here is the code:

This code is part of my "display" class:

function display_partner ($type,$loc,$rand=0,$narrow=0) {
$this->partners = new partner($this->cxn);
$display = '
<div id="cont_info" class="partner-list">
<div>
<h3 class="settings">'.ucfirst($loc).' '.ucfirst($type).last_letter($type).'s</h3>
</div>
<div class="settings-value" style="height:12px;padding:0;margin:0;text-align:right;padding-right:10px;">
<a href="" class="trunc">Add your organization to this list</a></p>
</div>
<div style="height:2px;padding:0;margin:0;">
<hr class="account" />
</div>
';
$ids = $this->partners->get_partners_list($type,$loc,$rand);
for ($b=0;$b<sizeof($ids->id);$b++) {
$this->partnerID = $ids->id[$b];
$display .= ($narrow)? $this->card_partner_narr():$this->card_partner();
if ($b!=(sizeof($ids->id)-1)) { $display .= '<hr class="account" />'; }
}

if (sizeof($ids->id)==0) {
$display .= '<div style="color:#999999;display:line;text-align:center;height:20px;">No Partners found for '.ucfirst($loc).' '.ucfirst($type).'</div>';
}

$display .= '
</div>';

return $display;

}

function card_partner () {
$this->partners->set_partner_id($this->partnerID);
$part_info = $this->partners->get_partner_info();
if ($part_info) {
$display .= '
<table class="settings">
<tr>
'.$this->show_if($part_info['partLogo']['val'],'<td class="settings-value" rowspan="2"><img src="'.LOGO_FOLDER.$part_info['partLogo']['val'].'" '.resize_img(LOGO_FOLDER.$part_info['partLogo']['val'],175).'alt="'.$part_info['partName']['val'].'" /></td>').'
<td class="settings-value" colspan="2"><h5>'.$part_info['partName']['val'].'</h5></td>
</tr>
<tr>
<td class="settings-value">
<span style="color:999999;">'.$part_info['partAddress']['val'].'<br />
'.$part_info['partCity']['val'].', '.$part_info['partST']['val'].' '.$part_info['partZIP']['val'].'<br />
'.$part_info['partPhone']['val'].'</span><br />
<a href="'.$this->form->show_href($part_info['partWeb']['val']).'" target="_blank">'.$part_info['partWeb']['val'].'</a>
</td>
<td class="settings-value">'.$part_info['partInfo']['val'].'</td>
</tr>
</table>
';
}

return $display;
}



This code is part of my "partners" class:

function set_partner_id($partID) {
echo '<p>partID: '.$partID.' '.gettype($partID).'<br>
$this->partner->id: '.$this->partner->id.'</p>';
$this->partner->id = $partID; ///*** ERROR HAPPENS HERE ***/
echo '<p>id set: '.$this->partner->id.'<br>
$this->partner->id: '.$this->partner->id.'</p><hr>';
}

function get_partner_id() {
return $this->partner->id;
}

// gets user info at login
function get_partner_info() {
$this->partner = $this->cxn->proc_info('partner','partID',$this->partner->id);//$this->partner->id
return $this->partner;
}


The following is the output generated:

partID: 24 string
$this->partner->id:
id set: 24
$this->partner->id: 24

partID: 26 string
$this->partner->id:
Warning: Attempt to assign property of non-object in /Users/staceyschaller/Sites/dev_zone/ckwv2/classes/class.php on line 670
id set:
$this->partner->id:

partID: 17 string
$this->partner->id:
id set: 17
$this->partner->id: 17


partID: 25 string
$this->partner->id:
Warning: Attempt to assign property of non-object in /Users/staceyschaller/Sites/dev_zone/ckwv2/classes/class.php on line 670
id set:
$this->partner->id:

As you can see, the value passes to $this->set_partner_id($partID) each time. It is formatted as a string. When it assigns the value to $this->partner->id, however, sometimes it works, and sometimes it doesn't. It's probably something obvious, but I've racked my brain to see what it is. Any ideas?

Hi guys, I have an interesting situation and I was hoping someone could explain what is going on to me.

I have an enquiry form on a site that sends an e-mail. All the code is on one page with the form submitting back to the same page. I have a variable, msg, which at the top of the page is set to nothing and then an if statement to see if the form was submitted. If the form was submitted then msg will have one of three messages in it by the end (regardless of anything else). However when I check the msg variable after the if statement it is empty.

To test if it was being affected I changed the initial value from nothing to TEST. After the IF statement the variable still held the value TEST, thus confirming it wasn't being affected by the IF statement. Now onto my code (the whole page is over 600 lines long so I'm only posting the relevant code):

Code: [Select]
<?php
session_start();
$msg = '';
$input = array(
24 variables from form here...
);
if(isset($_POST['form-submitted'])) {
$missing_info = FALSE;
$array = array(
variables along with their filter validation/sanitize types...
);
$input = filter_input_array(INPUT_POST, $array);
/* PHP validation code checking appropriate fields were not empty. If they were set $missing_info = TRUE */

if(!$missing_info) {
/* Construct e-mail, this sends successfully. */
if(mail($to, $subject, $content, $headers)) { 
$msg = '<div class="message"><h1>Form Sent</h1><br />Your form has been sent to us. We endevour to respond to all booking requests with 2 working days. If you have not heard from us in that time please contact us on 01462 893620. If you chose to confirm by post please allow 5 working days before contacting us.</div>';
$_SESSION['msg'] = $msg;
} else {
$msg = '<div class="message"><h1>Technical Issues</h1><br />We appologise but the website is currently experiencing technical difficulties. Please try again later or print this form out and post / fax it to us. Alternatively you can call us on 01462 893620.</div>';
$_SESSION['msg'] = $msg;
}
} else {
$msg = '<div class="message"><h1>Incomplete Form<h1><br />Please make sure to complete all fields of the form before submitting your booking request.</div>';
$_SESSION['msg'] = $msg;
}
}
if(isset($_SESSION['msg'])) { 
$msg = $_SESSION['msg'];
unset($_SESSION['msg']);
}
?>

If I don't load the message into session and then back out of session after the if statement then $msg will still hold whatever it was initially set to (in this case an empty string). Why isn't it set in the if statement?

Okay so after echoing awardType it says Match which would mean it would go to the else part of the statement but it doesn't. It still shows the dropdown for the characters and don't know why?

I've been baffled by this for 2 days now and cannot figure it out after exhaustive searches. I'd like to think I'm doing this correctly, but cannot get it to work.   I'm trying to use a variable within a query WHERE statement, and it shows 0 results. If I directly hardcode the text instead of using the variable, it works. The variable is pulling from a $_GET, and if I echo that variable, it is showing the correct text.   Here's my code:

$Domain = $_GET['Domain'];
$result = mysql_query(SELECT Code, Title, Domain, Status FROM tablename WHERE Domain="$Domain" ORDER BY Code');

If I swap out "$Domain" for direct text, like "ABC", it works. I have tried swapping out the quotes and single quotes throughout the statement, removing the quotes around $Domain, concatenating the statement separately....all yield erros or the same result.   And as stated, if I echo $Domain, it shows "ABC" (or whatever it's supposed to show), so i know it's pulling correctly from the $_GET.   Anyone know what I'm doing wrong?

I'm having an issue with holding a session variable in the statement below $Color is losing its value in the if statement. For example int the (   ) $Color is a zero while in the echo part $Color is being displayed correctly as Blue.

Hi,
My issue here is that I cant get my query string variables to ONLY feed into if/else statement  on my secondary page. I include my secondary page (fine.php) from my index page. My query string variables keep being fed back into my original if/ese statement on index.php.

here is the if/else on index.php (these links work fine):

<?php
if($_SERVER['QUERY_STRING']=='/index.php' || $_SERVER['QUERY_STRING']=='')
{
include 'port.php';
}

elseif (isset($_GET['pos'])){
include 'pos.php';
}

elseif (isset($_GET['web'])){
include 'web.php';
}

elseif (isset($_GET['fine'])){
include 'fine.php';
}

        else {include '404.php';}






here is the if/else on my secondary page (fine.php). These links are supposed to alert the if/else in the next table cell. However, they instead alert the if/else in index.php.


<td><br/>
<a href="?backset"><img src="fine/thumbs/x-backset.jpg" border="0"></a><br/><br/> 
<a href="?backside"><img src="fine/thumbs/x-backside.jpg" border="0"></a><br/><br/> 
<a href="?bannerprint"><img src="fine/thumbs/x-bannerprint.jpg" border="0"></a><br/><br/> 
<a href="?chopu"><img src="fine/thumbs/x-chopu.jpg" border="0"></a><br/><br/> 
</td>
<td><br/>
<div id="DivPiece" align="left">
<?PHP 

if (isset($_GET['backset'])){
       include 'fine/backset.php';
}

elseif (isset($_GET['backside'])){
     include 'fine/backside.php';
}

elseif (isset($_GET['bannerprint'])){
     include 'fine/bannerprint.php';
}

elseif (isset($_GET['chopu'])){
include 'fine/chopu.php';
}

?>
</div>
</td>



How can I get the links on the secondary page to only alert the if/else statement on that page, and BLOCK the if/else statement on index.php from seeing them? I still want to use the query string though.

Thanks!

Here's my echo statement for displaying comments by users.  I want to add a substr (); function to limit the amount of characters of the $comment field. That way if a user makes a long comment it doesn't push the page down.

I tried putting it after the echo ();  but that didn't work. I also tried putting it before $comment and that didn't even work. I know that if I make two separate echo statements, this can be done, but the field "$comment" is displayed within a table that is part of the original echo statement, so what do I do?

What's the correct syntax for having a variable in a select statement?

Here's an example of what I'm trying to do (after I'm already connected to the database).

Code: [Select]
$username = "thomas";
$query = mysql_query( "SELECT * from users WHERE username = $thomas" );
if( mysql_num_rows( $query ) > 0 )
{
bla bla...
It works if I don't put the WHERE part in, but I get an error if I use it, so I'm assuming I have the wrong syntax for using a variable in the select statement.

I have to put a link that can be clicked around the first name and last name variables in the echo statement below.  I also need to add a variable from the Select query to the link such as: 'www.phpfreaks.com/admin/customers.php?page=1&cID="VARIABLE HERE" &action=edit'

I've tried a bunch of things and none seem to work.


while($row = mysql_fetch_array($result)){


echo '<tr><td>' . $row['customers_firstname'] . " " . $row['customers_lastname'] . '</td><td>' .


date("M. d, Y", strtotime($row['date'])) . '</td><td>' . $row['plan_id'] . '</td></tr>';

OK, I think I have confused this code and it is not calculating correctly.
$ckifdue = mysql_query("SELECT * FROM accounting WHERE ClientID = '$clientid'") or die(mysql_error());
while($ckdue =mysql_fetch_array($ckifdue)){
    if($ckdue['AmountDue'] == "0"){
        $_SESSION['MONEYOWED'] = "0.00";
    }
    else
    {
       $_SESSION['MONEYOWED'] = $_SESSION['MONEYOWED'] + $ckdue['AmountDue'];
    }
    if($ckdue['Amount1RS'] == "Balance Due"){
        $totcol = $ckdue['TotalCollected'];
        echo " total collected:" . $totcol;
        $monpaid = $_SESSION['MONEYPAID'];
        echo "money paid in:" . $monpaid;
        $_SESSION['MONEYPAID'] =  $totcol + $monpaid;
        echo "session money paid:" . $_SESSION['MONEYPAID'];
    }
}
$moneypaid  = $_SESSION['MONEYPAID'];
$moneyowed = $_SESSION['MONEYOWED'];
echo "money paid:" . $moneypaid;
echo " money owed:" . $moneyowed;
$moneyowed = $moneyowed - $moneypaid;
unset($_SESSION['MONEYOWED']);
unset($_SESSION['MONEYPAID']);
The echos look like:

total collected:100.00money paid in:200session money paid:300 total collected:100.00money paid in:300session money paid:400money paid:400 money owed:0.00

There should be $100 due, $200 paid, so a balance of -100. There is 2 balance due reciepts, this is just not calclating right in the sessions.

I want to display some specific data from my database (just data from a given date).
I first created a page where the user picks the date. After the date is defined it is passed to the next page where the data from that date is displayed. That page includes a form where users can edit the data. The form data is then passed to a third page for processing. All of this works fine. Now I want the user to be taken back to the previous page with the assigned date.
On the processing page I am using this statement:
Code: [Select]
header("Location: /teetimes/adminteetimes.php?teetimedate=$dateID");and on the display page I'm using
Code: [Select]
$dateID = $_REQUEST[teetimedate];The display page is using a SELECT...WHERE Date='$dateID' statement and $dateID is defined in the processing page.
Problem is: I'm redirected from the processing page back to the display page but the date isn't passed, so the correct data isn't being displayed.
Can anyone help me pass a variable using a header?? Or show me where my logic is lacking??
Thanks!

Hello all,

I am a beginner at PHP and trying to form an IF statement, I'm running into a problem which I cannot seem to solve.
Due to my lack of syntax knowledge I would appreciate if someone could point me in the right direction.

The combo variables are sent to this page through a form and defined as these variables at the top of the page.
e.g $combo0 = $_POST["combo0"];

When the results are displayed any form field which was left blank or empty I want to show "N/A" if data is detected in being sent through the form I then want the "Else" statement to take affect.

Currently when I run the below statement N/A is echoed despite if data was sent through the form fields or not....

if (empty($scrap))  {
echo "<h3>Submitted Scrap Results</h3> No scrap parts were booked off";
}
elseif (empty($combo0) || empty($combo1) || empty($combo2) || empty($combo3) || empty($combo4)) {
echo "N/A";
}
else {
echo "<h3>Submitted Scrap Results</h3> <b>Reason:</b> " .$combo0." - ".$combo1." - ".$combo2." - ".$combo3." - ".$combo4."
<br /> <b>on machine</b> " .$mid. " - <b>No. Scrap</b> " .$noscrap. "";
}

Anyone any ideas?

Please take a look at the following code (this would work if the statement was SELECT instead of UPDATE) But I need to grab the following:

Code: [Select]
$result = mysql_query("UPDATE `AUCTIONS_MAIN` SET Current_Price = Current_Price + '$increase_price', Last_Bidder_Time = '$last_bidder_time' WHERE PId = '$id'");
//grab the new updated current price to save on different bidding history DB
while($row=mysql_fetch_array($result))
{
$current_price = $row['Current_Price'];
    }

As you can see, I need to give the new Current_Price value to the $current_price variable.
Obviously the while function is incorrect,
I would really appreciate any ideas and/or suggestions on how I can grab this value.

PS: I can't make a new query call with a select statement in order to know the new Current_Price. I need the direct updated value coming from the Update Statement, is this possible?

Thanks a lot in advance!!
