[RESOLVED] Trouble Going through an array..

ruhanir

Hi guys, really cracking my head why i can't loop through this array...

I'm calling a webservice which returns result in an array but if there is only one result i can't get an index for that array.. see below the code var_dump output which differs..

-- code ---

if (!$tx_elem == NULL) {
	foreach($tx_elem as $name => $value){
		echo "<tr>";
		echo '<td align="left" valign="top" class="grey12">'.date("M d Y",strtotime($value['TX-ELEM-DATE'])).'</td>';
		echo '<td align="left" valign="top" class="grey12">'.$value['TX-ELEM-VAL'].' '.$value['TX-ELEM-TYPE'].'</td>';
		echo "</tr>";
	}
	unset($value);
	var_dump($tx_elem);
	var_dump($name);
}

if there is only one transaction .. the var dump for $tx_elem output like below

    array
      'TX-ELEM-DATE' => string '20080330' (length=8)
      'TX-ELEM-TYPE' => string 'Points earned' (length=13)
      'TX-ELEM-PCI' => string 'NZNL' (length=4)
      'TX-ELEM-PCD' => string 'TEST CARD' (length=34)
      'TX-ELEM-VAL' => string '23' (length=2)

$name output like this ---

string 'TX-ELEM-VAL' (length=11)

but if there is more than one result then the $tx_elem return

array
  0 => 
    array
      'TX-ELEM-DATE' => string '20070521' (length=8)
      'TX-ELEM-TYPE' => string 'Points earned' (length=13)
      'TX-ELEM-PCI' => string 'CCTI' (length=4)
      'TX-ELEM-PCD' => string 'CCTI TESTING USAGE' (length=18)
      'TX-ELEM-VAL' => string '69' (length=2)
  1 => 
    array
      'TX-ELEM-DATE' => string '20070707' (length=8)
      'TX-ELEM-TYPE' => string 'Points earned' (length=13)
      'TX-ELEM-PCI' => string 'CCTI' (length=4)
      'TX-ELEM-PCD' => string 'CCTI TESTING USAGE' (length=18)
      'TX-ELEM-VAL' => string '100' (length=3)
  2 => 
    array
      'TX-ELEM-DATE' => string '20070707' (length=8)
      'TX-ELEM-TYPE' => string 'Points used' (length=11)
      'TX-ELEM-PCI' => string 'CCTI' (length=4)
      'TX-ELEM-PCD' => string 'CCTI TESTING USAGE' (length=18)
      'TX-ELEM-VAL' => string '-100' (length=4)
  3 => 
    array
      'TX-ELEM-DATE' => string '20070821' (length=8)
      'TX-ELEM-TYPE' => string 'Points earned' (length=13)
      'TX-ELEM-PCI' => string 'CCTI' (length=4)
      'TX-ELEM-PCD' => string 'CCTI TESTING USAGE' (length=18)
      'TX-ELEM-VAL' => string '52' (length=2)

and the $name returns

int 15

how can i check if the array has any index or not...? otherwise the distplay of the result fails

I am not sure what you are trying to do.
I also do not know
if you should perform anything outside of the foreach()

you can use this, to see
the contents of each $tx_elem

if (!$tx_elem == NULL) {
    echo '<pre>';
    foreach($tx_elem as $name => $value){
        print_r($name);
        print_r($value);
    }
    echo '</pre>';
}

actually i needed to show transaction records for user.. well if a user have only 1 transaction record then the array doesn't return any index, i mean $tx_elem wont have an index but if a user has more than one transaction record then $tx_elem will return index.. if you look at the response above you will know it..

for me i think i need to find a way to know that the $tx_elem has an array index assigned with it or not.. then i can display accordingly.. here is the output how u asked me to do..

if (!$tx_elem == NULL) {
	echo '<pre>';
	foreach($tx_elem as $name => $value){
		print_r($name);
		print_r('<br>');
    print_r($value);
		print_r('<br>');    

	}
	echo '</pre>';

user 1 (has only one transaction)

TX-ELEM-DATE

Points earned
TX-ELEM-PCI
NZNL
TX-ELEM-PCD
NEW ZEALAND NATURAL PRIVILEGE CARD

So You can see the same code returns one without array index and another with array index...

How about...

if (!$tx_elem == NULL) {
   if(isset($tx_elem['TX-ELEM-DATE'])) {
      $tx_elem = array(0 => $tx_elem);
   }
   foreach($tx_elem as $name => $value) {
      // etc....
   }
}

...?

ruhanir

you are the man.. NogDog

Thanks so much .. so i just needed to set the 1 record array to index 0 .. cool man

thanks a lot and really appreciate your help .. 😃

NogDog

Basically just converting the one-dimensional array into a 2-dimension array. Pretty kludgy, but it should work unless/until you can fix/enhance whatever function creates the array in the first place to be consistent in how it does so.

Well.. about that... I don't use any function to generate the array .. it's generated by 3rd party (.net :evilgrin: ) webservice.. the response called and generated via PHP NUSoap library.. .. thanks again.. i have another problem regarding the usage of nusoap to send update request to a webservice.. (for instance updating user profile information).. i've trying to solve it but still no use .. so most probably i'll post in the forum in a separate topic..
