php for each in while loop - php

Question

I am trying to get specific data from a while loop and loop it x number of times.
I'm selecting this data:
$r=mysql_query("SELECT ac6, ac5, ac4, ac3, ac2, ac1, ac0 FROM advertisements WHERE token = '".$_GET['token']."'");
while ($adData = mysql_fetch_array($r, MYSQL_NUM))
{
$data = $adData;
$ac0 = $data['ac0'];
$ac1 = $data['ac0'];
print $ac0;
print $ac1;
}
This doesn't work. Nothing gets printed out.
What I want to do is to get ac6 to ac0 value for that specific advertisement (where token).
How can I do that?

Answer 1

Change your numeric fetch to an associative one, then add a foreach loop to process the result.
$r = mysql_query("SELECT ac6, ac5, ac4, ac3, ac2, ac1, ac0
FROM advertisements WHERE token = '" . $_GET['token'] . "'");
while ($adData = mysql_fetch_assoc($r))
{
foreach ($adData as $key => $value)
{
$nubmer = (int)substr($key, 2);
print $value; // or whatever you actually want to do
}
}
Also I hope you're validating $_GET['token'] against possible mischief in your code.

You can create an arrays to add the values from the result query
1st is to create an array:
$advert_AC0 = array();
$advert_AC1 = array();
$advert_AC2 = array();
$advert_AC3 = array();
$advert_AC4 = array();
$advert_AC5 = array();
$advert_AC6 = array();
Now, to add content to array
$r = mysql_query("SELECT ac6, ac5, ac4, ac3, ac2, ac1, ac0
FROM advertisements WHERE token = '" . $_GET['token'] . "'");
if(mysql_num_rows($r)){ //check 1st if there is num of rows from the result
while ($adData = mysql_fetch_assoc($r))
{
array_push($advert_AC0, $dData['ac0']);
array_push($advert_AC1, $dData['ac1']);
array_push($advert_AC2, $dData['ac2']);
array_push($advert_AC3, $dData['ac3']);
array_push($advert_AC4, $dData['ac4']);
array_push($advert_AC5, $dData['ac5']);
array_push($advert_AC6, $dData['ac6']);
}
}else{
echo "NO RESULT.";
}
to call for the array values, 1 by 1
$count_array = count($advert_AC0);
$i = $count_array;
while(1 <= $i){
echo "AC0: $advert_AC0[$i]<br>";
echo "AC1: $advert_AC1[$i]<br>";
echo "AC2: $advert_AC2[$i]<br>";
echo "AC3: $advert_AC3[$i]<br>";
echo "AC4: $advert_AC4[$i]<br>";
echo "AC5: $advert_AC5[$i]<br>";
echo "AC6: $advert_AC6[$i]<br>";
$i++;
}
I don't know if my answer solved your question, please comment if not.
