[SOLVED] easy - get data out of an array

[teknojunkey]

Hi , im trying to get the data out of an array.

 

I can see the array using this:

print_r($_SESSION); 

 

this is printed:

Array ( [submitted] => Array ( [1] => Array ( [code] => Array ( [4mmPilkingtonMinisterToughened] => TRUE ) ) [3] => Array ( [code] => Array ( [RecetrackCutimgsrcimagesracetrack.jpg] => TRUE ) ) [4] => Array ( [other] => 10 ) [5] => Array ( [other] => 200mm ) [6] => Array ( [other] => 200mm ) ) ) 

 

I want to get the following out of the array and displayed without the "other bits":

 

"4mmPilkingtonMinisterToughened" "RecetrackCutimgsrcimagesracetrack.jpg" "10" "200mm" "200mm"

 

Im a bit of a newby so please be gentle.

 

thanks

You need teh foreach loop.

 

foreach($_SESSION['submitted'] as $key => $value) {
$data[]['key'] = $key;
$data[]['value'] = $value;
} 
echo $data[0]['key'] . "\n";
echo $data[1]['key'] . "\n";
echo $data[2]['value'] . "\n";
echo $data[3]['value'] . "\n";
echo $data[4]['value'] . "\n";

 

we are putting the array keys and values in an array and selectively fishing them out.

$_SESSION['submitted'][1]['code'] should contain the value you're looking for, based on the print_r() you posted.

Thanks I got the first item in teh array out , but nothing els.

 

I used this :

 

foreach($_SESSION['submitted'][1]['code'] as $nkey => $nvalue) {

$data[]['nkey'] = $nkey;

$data[]['nvalue'] = $nvalue;

}

print_r ($data[0]['nkey'] . "\n");

print_r ($data[1]['nvalue'] . "\n");

print_r ($data[2]['nkey'] . "\n");

print_r ($data[3]['nvalue'] . "\n");

 

can i replace the [1] with a wildcard ? if there is one

thanks

I guess i should give a url: http://dev.crocodile-communication.com/demoshop/ask/survey.php?sid=1568D5

 

the problem is on the following pages:  print_r($_SESSION); seems to work fine , but with the syntax stuff.

i have figured out what i want to do ,

 

I want this to display the new data in the array as it is added.

 

foreach($_SESSION['submitted'][1]['code'] as $nkey => $nvalue) {

$data[]['nkey'] = $nkey;

$data[]['nvalue'] = $nvalue;

}

print_r ($data[0]['nkey'] . "\n");

print_r ($data[1]['nvalue'] . "\n");

print_r ($data[2]['nkey'] . "\n");

print_r ($data[3]['nvalue'] . "\n");

 

currently it only displays the first item in the array, is it possible to update the output text at the array is updated?

 

thanks

Hi

is it possible to update the output text as the array is updated?

 

foreach($_SESSION['submitted'][1]['code'] as $nkey => $nvalue) {

$data[]['nkey'] = $nkey;

$data[]['nvalue'] = $nvalue;

}

print_r ($data[0]['nkey'] . "\n");

print_r ($data[1]['nvalue'] . "\n");

print_r ($data[2]['nkey'] . "\n");

print_r ($data[3]['nvalue'] . "\n");

 

the number 1 should change to show the other keys in the array

[premiso]

foreach($_SESSION['submitted'][1]['code'] as $nkey => $nvalue) {
$data[]['nkey'] = $nkey;
$data[]['nvalue'] = $nvalue;
}

$cnt = count($data);
for ($i=0; $i<$cnt; $i++) {
print_r ($data[$i]['nkey'] . "\n");
print_r ($data[$i]['nvalue'] . "\n");
}

I have to modify and add this for each item in the array :

 

foreach($_SESSION['submitted'][1]['code'] as $nkey1 => $nvalue1) {

$data1[]['nkey1'] = $nkey1;

$data1[]['nvalue1'] = $nvalue1;

}

$cont1 = count($data1);

for ($i=0; $i<$cont1; $i++) {

print_r ($data1[$i]['nkey1'] . "\n");

print_r ($data1[$i]['nvalue1'] . "\n");

}

echo "<br>";

//------------------------------------------------------------

 

foreach($_SESSION['submitted'][3]['code'] as $nkey3 => $nvalue3) {

$data3[]['nkey3'] = $nkey3;

$data3[]['nvalue3'] = $nvalue3;

}

$cont3 = count($data3);

for ($i=0; $i<$cont3; $i++) {

print_r ($data3[$i]['nkey3'] . "\n");

print_r ($data3[$i]['nvalue3'] . "\n");

}

 

No great, but it now works thanks for your help:)
