I have a textarea in which users write like this:
- 3x Blue Flower
- 2* Red Flower
- 5 Purple Flower
- Yellow Flower
The point is to echo Blue Flower 3 times etc., while flowers that don’t have numbers are echoed 1 time.
This is my code:
$str = $_POST['tekst'];
$input = explode("n", $str);
foreach($input as $line)
{
preg_match("/d+/", $line, $matches);
$line = preg_replace("/d+/",'' ,$line);
$number = (isset($matches[0]))?$matches[0]:1;
if(strlen($line)>0){
foreach ($line as $k=>$val)
{
$temp_second_field = $number[$k];
for ($i = 0 ; $i < $temp_second_field ; $i++ )
{
echo $val;
}
}
}
}
Answer
It is because $line is not an array, it is a string. Try replacing this :
// foreach ($line as $k=>$val)
// {
// $temp_second_field = $number[$k];
// for ($i = 0 ; $i < $temp_second_field ; $i++ )
// {
// echo $val;
// }
// }
//$temp_second_field = $number[$k];
with this:
for ($i = 0 ; $i < $number ; $i++ )
{
echo $line;
}
