Hello, all. Please advise how to use $_POST in cycle. I have the following code:
I have tried:
...but it doesn't work. :(
The problem i see is here $id".$x." = $_POST['id".$x."'];
you can't concat a string onto a variable name, you should use an array for that eg.
<?php
$ids = array();
for ($x=1; $x<=3; $x++){
if (isset($_POST['id'.$x])) {
$ids[] = $_POST['id'.$x];
}
}
var_dump($ids);
?>
When you concat you need to make sure you use the same quote the string was started with, when it starts with a single quote it needs to close with another single quote - a double quote will just be put in the string literally and vice versa when it is opened with a double quote and you type a single quote inside it.
You could do something like this below for any number of id fields:
$ids = array();
foreach($_POST as $k=>$v){
if(substr($k,0,2) == 'id'){
$ids[] = $v;
}
}
foreach($ids as $v){
echo $v."<br/>\r\n";
}
Within the loop:
$var = 'id' . $x;
$$var = isset($_POST[$var]) ? $_POST[$var] : '';
