PHP - Array Has Contents, But Won't Echo...

How can I echo the array value?

Here is the pre...

Array
(
    => Array
        (
            [count] => 2
        )

)

Here is my currrent code...

Code: [Select]
<span class="blue"><?php echo $count; ?></span>

Can I do this without using a foreach loop?

Hello,   I am working on this function that echo's out images from my database restricted to 10 images with 4 default images if the database is empty.

<?php 

$query = mysql_query('SELECT image_id, image_expiry FROM images ORDER BY RAND() LIMIT 10');

$i = 0;
					
class myCounter3 implements Countable {
public function count() {
static $count = 0;
return ++$count;
}
}
						
$counter = new myCounter3;

while ($row = mysql_fetch_array($query))

{

if($i % 10 === 0)

{


}

echo	'<img src="http://www.mysite.com/'.$row['image_id'].'.jpg" width="300" height="auto"/>';
								
$i++;

}

for (; $i <= 4; $i++) {

echo '<img src="http://www.mysite.com/default.jpg" width="300" height="auto"/>'

}

?> 

I need to include an image expiry function with the function above, but I am not sure how to properly include it.   Here is my planned expiry function (each image as an expiry date).

$today = date("Y-m-d", time());

$expiry = $row['image_expiry']

if( $today > $expiry)
   {
   ## ignore expired image
  }
else
   {
   ## display image
  }

Bottom line I need to exclude expired images from being echoed out in the first function.   Thanks in advance.  Everything I have tried hasn't worked.    

How can I echo the $id?  Every time I post approved it refreshes my page and I can see the echoed out ID.  I need to know what the ID value is.
Code: [Select]
if (isset($_POST['approve']))
{
if(is_array($_POST['approve'])) {
$keys = array_keys($_POST['approve']);
$id = $keys[0];

echo $id;
die();
//$sql = "UPDATE `blog_comments` SET `approved` = 1 WHERE `post_id` = '$id'";
//header("Location: " . $_SERVER['PHP_SELF'] . "?" . $_SERVER['QUERY_STRING'] );
}
}

Hey guys,   I am using a function that echos out 10 images from my database.  I need to have a minimum of 4 echoed images.  Some categories have less than 4 images, so I would like to have a default image(s) echoed out if the database has 4 or less images.   Does anyone know how I can do this?   Below is the code I am using now to echo out the 10 images.   Thanks in advance:

 <?php 
		 
		 	 

                    $query = mysql_query('SELECT image_id FROM images ORDER BY RAND() LIMIT 10');

                    $i = 0;
					
					class myCounter3 implements Countable {
							public function count() {
								static $count = 0;
								return ++$count;
							}
						}
						
						$counter = new myCounter3;

                    while ($row = mysql_fetch_array($query))

                    {

                        if($i % 10 === 0)

                        {


                        }

                        echo	'<img src="http://www.mysite.com/'.$row['image_id'].'.jpg" width="300" height="auto"/>';
								
                        $i++;

                    }

                ?> 

Default Image: <img src="http://www.mysite.com/default.jpg" width="300" height="auto"/>

I have an array ( $exifdata ) which contains the relevant bits that I require, read from exif data, as in the var_dump below.

array
  0 => string 'Caption' (length=7)
  1 => string 'Copy' (length=4)
  2 => string 'Camera' (length=6)
  3 => string 'Shutter' (length=7)
  4 => string 'fNo' (length=3)
  5 => string 'ISO' (length=3)
  6 => string 'Date' (length=4)
  7 => string 'Time' (length=4)
  'copy' => string 'Alf Thomas' (length=10)
  'caption' => string 'Blue Sky over Auld Reekie' (length=25)
  'camera' => string 'Canon PowerShot G9' (length=18)
  'shutter' => string '1/800' (length=5)
  'fNo' => string 'f/5.6' (length=5)
  'iso' => int 200
  'date' => string '07:10:2011' (length=10)
  'time' => string '09:05:26' (length=8

What I am trying to do is echo each key followed by its relevant data, and thought something like this would work:-

Code: [Select]
foreach( $exifdata as $key => $value){
echo "$key :, $value <br />";
}
The output I get from the above is as below:-

0 :, Caption
1 :, Copy
2 :, Camera
3 :, Shutter
4 :, fNo
5 :, ISO
6 :, Date
7 :, Time
copy :, Foucquet
caption :, Blue Sky over Auld Reekie
camera :, Canon PowerShot G9
shutter :, 1/800
fNo :, f/5.6
iso :, 200
date :, 07:10:2011
time :, 09:05:26

Which more or less does what I want except that what I actually would like is this:-

Copy - Foucquet
Caption - Blue Sky over Auld Reekie
Camera - Canon PowerShot G9
Shutter - 1/800
fNo - f/5.6
ISO - 200
Date - 07:10:2011
Time - 09:05:26

What I can't quite understand is why I am getting the two lists as an output, which simply seems to be identical to the output of the var_dump.

I have peice of code which is designed enter a question into a database and the username of the person who asks the question.

However, the code enters <?php echo Array; ?>  into the database and  not 'Tom'.

I am using the same code which inserts the category of the question in the database which works.  But the username comes up as <?php echo Array; ?>.  Does anyone know why it shows "array"?


Code: [Select]
if($loggedIn) {
    echo "Welcome, ".$user['username'].". <a href=\"logout.php\">Logout</a>.
<table width='300' border='0' align='center' cellpadding='0' cellspacing='1'>
<tr>
<td><form name='form1' method='post' action='phpviewquestion.php'>
<table width='100%' border='0' cellspacing='1' cellpadding='3'>
<tr>
<td colspan='3'><strong>Your Question</strong></td>
</tr>
<tr>
<td width='71'>Question</td>
<td width='6'>:</td>
<td width='600' height='50'><input name='question' type='text' id='question'></td>
<td width='71'>Notes</td>
<td width='6'>:</td>
<td width='600' height='50'><input name='notes' type='text' id='notes'></td>
</tr>
<tr>
<td colspan='3' align='center'><input type='image' name='image' value='Submit' src='http://www.domain.co.uk/images/submitbutton.PNG' name='image' width='100' height='53'></td>
<input name='category' type='hidden' value='Furniture' id='category' >
<input name='questionmaker' type='hidden' value='<?php echo $username; ?>' id='questionmaker' >
</tr>
</table>
</form>
</td>
</tr>
</table>

</div>
"
;
} else {
    echo "Please <a href=\"login.php\">Login</a>.";
}

Hi There, 

I'm feeling really dumb but i can't figure out how to get the data from an array that has been converted from xml so I can put it into a table.

I've tried looping through based on simple array code but i just get array to string errors.

my code looks like this

$projects = array();    
    
    
        $xml=simplexml_load_string($response) or die("Error: Cannot create object");
        
    foreach($xml->Jobs->Job as $item) {
        
    $projects[] = array(
                     'job_no'          => (string)$item->ID,
                     'job_name'        => (string)$item->Name,
                     'job_due'         => (string)$item->DueDate,
                    );


//array_sort_by_column($projects, 'job_due');

print_r($projects); 

print_r just dumps the whole lot on the page. Id like to grab each of those items and put them in a table cell then sort them by the due date etc.  

$job_no ="";
$job_name ="";
$job_due ="";       
        
        
        
        //$item1 = $item->Client->Name;
        //$job_no = "$item->ID";
        //$job_name = "$item->Name";
       // $job_client = "$item1";
        //$job_start = "$item->StartDate";
        //$job_due = "$item->DueDate";
        //$job_status = "$item->State";
        $date = new DateTime($job_due);
        $due_date = $date->format('d-m-Y');
        

    
    echo "<tr>";
    echo "<td><a href='managejob.php?job_id=$job_no'><strong>$job_no</strong></td>";
    echo "<td>$job_name</a></td>";
    echo "<td>$job_priority</td>";
    echo "<td>$job_status_1</td>";
    echo "<td>$job_status_2</td>";
    echo "<td>$job_status_3</td>";
    echo "<td>$job_status_4</td>";
    echo "<td>$job_status_5</td>";
    echo "<td>$job_status_6</td>";
    echo "<td>$job_status_7</td>";
    echo "<td>$due_date</td>";
    echo "</tr>";
    } 
}

Any help on this would be much appreciated. Thanks in advance.

Hello, im new here, and i have little experience to php and mysql as i started for 2 weeks ago.
I started out with some tutorials and feeling im getting the hang of it.

Enough of me, lets get to the point:
<?php

$con = mysql_connect('localhost',$user,$pass)or die(mysql_error());
$selectdb = mysql_select_db($selectdb)or die(mysql_error());

$sql = "SELECT * From table";
$result = mysql_query($sql);
$num = mysql_num_rows($result);
$myarray = array($result);
$i =0;

while ($i < $num){

echo $myarray[$i];
$i++;
}

?>

Here i have written a dummyscript that does what the original script does, it tries to fetch the keys from the table and then trying to loop it and echo out the results.
The output in the browser is this: Resource id #3

I know this probably is a simple fix but i cant seem to get it sorted out. Hope some of you could help me get this baby work, or maybe have another way of doing it more "simple".


Thanks in advance!

Hello everyone, i'm kinda stuck here although i had this working before,  i don't know what's wrong here.

Basically i've got a form with a drop-down menu, that menu has 3 values, x,y and z. Now that form is working with post, sending me to the next page where i have a set of arrays and a echo which should print some text based on the option chosen from the drop down menu.

my code in the form is this:

Code: [Select]
<select name="value1" id="value1">
        <option value="x">x</option>
        <option value="y">y</option>
        <option value="z">z</option>
      </select>
the array on the next page:

Code: [Select]
$arrayvalue = array("x"=>"test1", "y"=>"test2", "z"=>"test3");
and the echo:
Code: [Select]
<?php echo $arrayvalue["value1"];?>
That leaves me with an empty page. What am i doing wrong here ? am i missing something ?

any help is greatly appreciated.

Hi! My question is probably simple but I've been scratching my head for hours now... I'm pretty new to php. I have an online form for orders; when submitted, an email is sent to the shop manager containing the info the client has filled in. So I pass all the info in the code below, but I can't manage to echo the array containing the order's items/qty/item_code. (I'm using Wordpress, Oxygen Builder, Metabox and Code Snippets, if that helps). Here's the code (used as a Code Snippet):

add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
    if ( 'command-form' !== $config['id'] ) {
        return;
    }

    $name = rwmb_meta( 'name', '', $post_id );
    $email = rwmb_meta( 'email', '', $post_id );
    $phone = rwmb_meta( 'phone', '', $post_id );
    $orders = rwmb_meta( 'order', '', $post_id ); */ ---> this is the array I wish to show the elements from (array --> [0]:{item:"item", qty:"qty", code:"code"]}, [1]:{}, etc...} */
    $comments = rwmb_meta( 'comments', '', $post_id );
    $reception = rwmb_meta( 'reception', '', $post_id );
    $destination = rwmb_meta( 'destination', '', $post_id );
    $payment = rwmb_meta( 'payment', '', $post_id );

    $body = "Vous avez reçu une nouvelle commande en ligne!

Nom: $name
Courriel: $email
Téléphone: $phone
Commande: */ ---> this is where I want it displayed, but since it is within $body = " ", I can't seem to be able to use foreach( ) or even print_r( )... */
Commentaires: $comments
Réception: $reception
Paiement: $payment";
     

    $headers = ['Content-type: text/html', "Reply-To: $email"];
    wp_mail( 'address@domain.com', 'Nouvelle commande en ligne', $body );
}, 10, 2 );

 

Help with this would be greatly appreciated! Please let me know if any details are missing. Thanks in advance!
