PHP - Variable Variables And Other 90's Stuff...

If I knew what to call it I could have searched it.  So I will just explain.

I have a form that is pulling from a database to build the following.
echo <input name='$row[id]' type='text' id='$row[id]' size=2>;

This will build a page that has this
<input name='22' type='text' id='22' size=2>
<input name='54' type='text' id='54' size=2>

This part works great.  The problem is when I try to add it to the database.  How can I insert variables that I don't know the names of?  They will be something like $_POST[22]   $_POST[54] and so on.  I hope someone can understand my jibberish.

I am sure there is a WAY better way to do this.

I know how to use $$ and ${} to use variable variables, but how would I get the same functionality out of a variable that is storing an object name?

I have a function that is passed the name of an array of objects.  As you can guess, that name will change based on which portion of the program is calling
the function.  How would I use variable variables of objects in this instance?  Would it just be:

Code: [Select]
$this->${$objArrayName}->threadName = etc;
?

To make sure I'm not being misunderstood, I have 3 arrays of objects (replies, mainThreads, and stickies) and depending on which name I pass the function, I want it
to use $this->replies OR $this->mainThreads OR $this->stickies to apply properties of those objects to.

Thanks for any help.

Is it possible to split a variable into 2 variables?


///  I have this sentence
$item = "Below Telegraph Hill, Smallwork Canvas Edition";

/// And I want to be able to do this
$item = "Below Telegraph Hill" ;
$medium = "Smallwork Canvas Edition";


Is it possible to find the comma in a string, and remove the comma & everything before or after it? Any recommendations would be appreciated.

I'm not versed in PHP OOP and I have some code that I need to echo out onto a page. I don't know what the meaning of $ct->something is in this code. Is this an array of some type? How do I echo out the $ct->title onto another page? Use a function call? I just don't know what all of the $ct variables are and how to get to them. Any help is appreciated.
Code: [Select]
function current_theme_info() {
    $themes = get_themes();
    $current_theme = get_current_theme();
    if ( ! isset( $themes[$current_theme] ) ) {
        delete_option( 'current_theme' );
        $current_theme = get_current_theme();
    }
    $ct->name = $current_theme;
    $ct->title = $themes[$current_theme]['Title'];
    $ct->version = $themes[$current_theme]['Version'];
    $ct->parent_theme = $themes[$current_theme]['Parent Theme'];
    $ct->template_dir = $themes[$current_theme]['Template Dir'];
    $ct->stylesheet_dir = $themes[$current_theme]['Stylesheet Dir'];
    $ct->template = $themes[$current_theme]['Template'];
    $ct->stylesheet = $themes[$current_theme]['Stylesheet'];
    $ct->screenshot = $themes[$current_theme]['Screenshot'];
    $ct->description = $themes[$current_theme]['Description'];
    $ct->author = $themes[$current_theme]['Author'];
    $ct->tags = $themes[$current_theme]['Tags'];
    $ct->theme_root = $themes[$current_theme]['Theme Root'];
    $ct->theme_root_uri = $themes[$current_theme]['Theme Root URI'];
    return $ct;
}

$orange = 'Orange';
$apple = 'Apple';

 

Hello,

If I have this string:

$tags="baseball glove face" (this can vary from 1 to 15 different words)

how would i loop through and divide these into different

$tag1=baseball
$tag2=glove
$tag3=face
.. and so on (if more words)

Thanks for help

I am trying to achieve something that appears simple but  I spent few hours in vain



Quote

$tag1 = '<a href="layout_m.php?k='.$k.'&name='.$name.'&type='.$type.'">';

if ($k=="1") {$history = ucfirst($name) . ' - ' . $tag1 . $k .'</a>'  ; }
else {$history = $history . ' - '. $tag1 . $k . '</a>' ;}

print $history;



This is part of a page which is involved in passing data by forms or/and URL (eg layout.php?k=1) and the display of the page depends on k.


At k=1,(first page)  things are ok [Joe -  <a href="layout_m.php?k=1&name=Joe&type=genus"> 1 </a>]

but on passing to the next page, the output is not as desired

part of the variable is escaped out on the browser and breaks the variable content


View source gives this:
Joe -  <a href= -  <a href="layout_m.php?k=3&name=Joe&type=genus"> 1 </a>

while I want:

Joe -  <a href="layout_m.php?k=1&name=Joe&type=genus"> 1 </a> -  <a href="layout_m.php?k=3&name=Joe&type=genus"\> 3 </a>

What I achieve to do is a simple history based on an accumulation of k

EG Joe - 1 - 3 - 5 - 6 - 8  Where each number (k) is linked and when pressed each go to the corresponding keypage.

I have this simple while loop which retrieves data from a mysql query and displays several links on my homepage.

I would like to avoid using the php get function and add query strings to my urls

I am thinking of using session variables but I need help and I'm pretty sure this can't be done.

When a visitor clicks a link from the several ones displayed by the while loop, that particular variable would be set in a session.

In my code, the session will always send the last var

Can this be done?

    Code: [Select]
<? session_start(); // Start Session Variables

    $result = mysql_query("my query");

    while($slice = mysql_fetch_assoc($result)){
        $url = $slice['url'];
        $name  = $slice['name']; ?>

        <a href="<? echo $url; ?>"><? echo $name; ?></a>

    <? }

    $_SESSION['name'] = $name; // Store session data  ?>

First page adds a new job number, then the order page loaded with the job number id as a get id. Basically there is a while loop in the order page which shows products/services client can order and he chooses what he requires 'one or eight services' (8 in total) and some other variables like date of order and client name etc. Here is the order item code

The first sql statement executes fine, but in the second sql query nothing happens


$sql="insert into job_order(order_num,order_date,order_customer_id, order_remarks) values(".$_GET['id'].",NOW(),".$_POST['companyBox'].",'".$_POST['remarkBox']."');"; $res=mysql_query($sql);  $id=mysql_insert_id();   foreach($_POST as $key => $value) {          if(!empty($value)) {           $key.' => '.trim(strip_tags($value));            $order="INSERT INTO orderprod (order_num,prod_id,order_amount,teeth_amount) VALUES ('$_GET[id]','$value','$value','$value');"; $orderres=mysql_query($order) or die(mysql_error()); } }?>$sql="insert into job_order(order_num,order_date,order_customer_id,
order_remarks)
values(".$_GET['id'].",NOW(),".$_POST['companyBox'].",'".$_POST['remarkBox']."');";
$res=mysql_query($sql);

$id=mysql_insert_id();


foreach($_POST as $key => $value) {


        if(!empty($value)) { 
 
         $key.' => '.trim(strip_tags($value));  
     
         $order="INSERT INTO orderprod (order_num,prod_id,order_amount,teeth_amount) VALUES
('$_GET[id]','$value','$value','$value');";
$orderres=mysql_query($order) or die(mysql_error());
}
}
?>

This is the formI have removed parts which are irrelevant. Please note that dateBox and companyBox are not required to be looping as they are only for first table,

hello guys, i'm new here, looking for some help..

here is the situation:

Why is it when a save a youtube video on my db it gives me this

&lt;iframe width="220" height="240" src="http://www.youtube.com/embed/DCZ2l1BbWyY?wmode=opaque" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;<br>

i have to save it twice so it can be view why if you want to see my edit videos page i will add it here

I have a string:
"system_controllers_qty"

and i need it to be:
"system_controllers.system_controllers_qty"

I can use substr because the It wont always be 'system_controllers', it can be 'system_cpus' for example so I need to somehow break and the second underscore if possible. Any ideas?

This script is working fine on PHP 5.3.1 but i got a new host that uses 5.3.6 and now its no longer working? What can i change to make it work, and does anyone know where i can learn the different coding between the 2 updates?

Code: [Select]
<?
include 'cpheader.php';
if (isset($_POST['submit'])) {
$error = ($_POST['title'] == "") ? "You need to have a title!" : $error;
$error = ($_POST['message'] == "") ? "You need to have a message!" : $error;
if($error == ""){
$time = time();
$result= mysql_query("INSERT INTO `ads` VALUES('".$time."', '$user_class->id', '".$_POST['title']."', '".$_POST['message']."')");
echo Message("You have posted a news update.);
} else {
echo Message($error);
}
}
?>
