Assign Variable From Link?

I have a page that lists out some basic information about each quiz this particular student has taken (call it "quiz summary"). I am creating another page that will have all details of a particular quiz by itself (call it "quiz detail").

If I have a link for each quiz on the "quiz summary" page, how do I tell the "quiz detail' page which link they clicked on? Or which quiz they have selected.

I was thinking it would work if I assigned a session variable to each link and then the "quiz detail" page could verify which returns true still and show details for that quiz. Would this logic work? Npot sure how to do it anyone though.

thanks for any help!

Can A $_post[$variable] Use A Variable In The Argument Position?

I have a form that creates rows of data input textboxes depending on a user input number of things. I have a naming convention for all these textboxes that basically just keeps incrementing a number suffix for each row. All this is working fine.

My problem is I need to get the data inserted into this table of textboxes into an array.

Here's my code where I attempt to to this (it does not work):

Code: [Select]
$temp = $_SESSION['Num_Part'];
$count = 1;
while ($count <= $temp){
$temp2[$count] = "'Participant_P".$count."'";
//echo $temp2[$count]."<br/>";
$temp3[$count]=$_POST[$temp2[$count]]; //here's the problem
$temp4[$count] = "'Result_P".$count."'";
$temp5[$count]=$_POST[$temp4[$count]]; //here's the problem
//echo $temp4[$count]."<br/>";
$count++;
}

The problem is that the $_POST does not work with the variable in the argument position - even though the argument is formatted with single quotes.

Can a variable be used in a POST argument and if so what is the correct syntax?

If not, is there some other simple solution to harvest the data into an array. I understand I can harvest by explicitly accessing each key in the post assoc array. But this could be dozens of rows of input fields.

Thanks in advance for your help here. I couldn't find anything online re this topic.

User clicks on a url, ie: example.com/AEQ438J

When I perform this in the code below:

Code: [Select]
$referrer = $_GET['_url'];
// echo $referrer displays the referrer ID contents correctly as "AEQ438J"

if ( ! empty($referrer))
{
$mysqli->query("UPDATE coming_soon_emails SET clicks = clicks + 1 WHERE code='" . $referrer ."'");
}
// this also updates the database correctly as it should

if (!empty($_POST['email'])){

// echo $referrer displays the referrer ID contents as BLANK. It should display "AEQ438J"!
.....
$referrer displays correctly BEFORE if($_POST['form']), however during the if($_POST['form']) $referrer is empty.
How can I fix my code so that $referrer is not empty during the time the user posts their email address in the form?

Thank you!

Get "attempt To Assign Property Of Non-object" Warning When Assigning Variable

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?

Preg_replace() Pattern "/ /" Delimiter Will Not Work With $_post Variable.

preg_replace() asks that "Delimiter must not be alphanumeric or backslash" in the pattern. So I changed

$new_text = preg_replace($_POST['withthis'] ,$_POST['withthis'],$_POST['text']);
to this
$replacethis = $_POST['replacethis'];
$new_text = preg_replace("/$replacethis/",$_POST['withthis'],$_POST['text']);
It works fine, but out of curiosity, is there any way to have the POST variable as a parameter directly, and why does it not work?

Just to try it, I attempted: "/$_POST['withthis']/" and $_POST["/'withthis'/"] and both do not work. str_replace is a better option I think, but I am just trying to get a better understanding of this delimiter rule. Thanks for your time!

A $_post['titel[$n]'] Problem

I'm making a script for editing lines in a text file.

PHP code form form script:

$n = 0;
$bestand = "../test.txt";
$gegevens = file($bestand);

//count lines titel.txt
$lines = count(file($bestand));

while($n < $lines) {
$items = explode("|", $gegevens[$n]);
$titel = $items[0];
$beschrijving = $items[1];
$n=$n+1;

echo "<tr>
<td><input type=\"text\" class=\"edit\" name=\"titel[".$n."]\" value=\" ".$titel." \" /></td>
<td><textarea name=\"beschrijving[".$n."]\">".$beschrijving."</textarea></td>
</tr>";
}

Code of processing script

<?php
$n = 1;

$bestand = "../test.txt";
$lines = count(file($bestand));

while($n < $lines){

//Set variables
$titel = $_POST['titel[$n]'];

//Replace 'Enter' for '<br />'
$_POST['beschrijving[$n]'] = preg_replace ("#\r?\n#", '<br />', $_POST['beschrijving[$n]']);
$beschrijving = $_POST['beschrijving[$n]'];

//Write $titel
$handle = fopen($bestand, "a");
fwrite($handle, "".$titel."|");
fclose($handle);

//Write $beschrijving
$handle = fopen($bestand, "a+");
fwrite($handle, "".$beschrijving." ");
fclose($handle);

$n=$n+1;
}
?>

De form scripts works fine, no problems. But the processing script give me the next notices:

Code: [Select]
Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10 Notice: Undefined index: beschrijving[$n] in /var/www/NellekeTekent/cms/edit.php on line 13 Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10 Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10 Notice: Undefined index: titel[$n] in /var/www/NellekeTekent/cms/edit.php on line 10
I gues the problem is '$n' when setting $titel and $beschrijving.
But I don't know how to solve it.
Can you help me?

Hi there I'm trying to make this form submit...but alas, is to no avail .... i have two forms on top of each other one of them is:

Code: [Select]
<form name="entries_form" method="post" action="index.php">
<table>
<tr>
<th><label>Date</label></th>
<th><label>From</label></th>
<th><label>To</label></th>
<th><label>Break</label></th>
<th><label>Hours</label></th>
<th><label>Required Hours</label></th>
<th><label>Notes</label></th>
</tr>
<tr>
<td>

<input name="Date" type="text" id="Date" />
</td>
<td>

<input name="From" type="text" id="From" />
</td>
<td>
<input name="To" type="text" id="To" />
</td>
<td>

<input name="Break" type="text" id="Break" />
</td>
<td>

<input name="Hours" type="text" id="Hours" />
</td>
<td>

<input name="Rqrd_hrs" type="text" id="Rqrd_hrs" />
</td>
<td>

<input name="Notes" type="text" id="Notes" />
</td>
<td>
<input type="submit" name="Save" value="Save" id="Save" style="background-color:#7A70A4;" />
</td>
</tr>
</table>
</form>
to post i'm using this code (to much over the top maybe):
Code: [Select]
<?php

$session = new Session();
$u_id = $session->get('id'); //to get the user id from session

if(isset($_POST['submit']) == 'Save'){//form's button  name is Save
$entry->user_id = $user_id = $u_id;
        $entry->date = $date = trim(strtolower($_POST['Date']));
        $entry->start_time = $start_time = trim(strtolower($_POST['From']));
        $entry->end_time   = $end_time   = trim(strtolower($_POST['To']));
$entry->breaks      = $break   = trim(strtolower($_POST['Break']));
$entry->total_hours   = $total_hours   = trim(strtolower($_POST['Hours']));
$entry->reqd_hours   = $required_hours   = trim(strtolower($_POST['Rqrd_hrs']));
$entry->notes   = $notes   = trim(strtolower($_POST['Notes']));

        $entry->add_entry();
    }else die("Not Posted");
    ?>
the add entry() function does the following:
Code: [Select]
public function add_entry(){
global $database;
$sql = "INSERT INTO sheetentries (";
$sql .= "user_id, date, start_time, end_time, break, required_hours, total_hours, notes";
$sql .= ") VALUES ('";
$sql .= $this->user_id ."', '";
$sql .= $this->date ."', '";
$sql .= $this->start_time ."', '";
$sql .= $this->end_time ."', '";
$sql .= $this->breaks ."', '";
$sql .= $this->reqd_hours ."', '";
$sql .= $this->total_hours ."', '";
$sql .= $this->notes ."')";
$database->query($sql);
}
the user_id or $u_id brought from the session when the user loggs in:
Code: [Select]
$u_id = $session->get('id');
anyway, whenever i try submitting the form nothing happens, what am i missing,,, thanks in advance
