I have the required ID variable from this, (there are 1-6 possible values):
$new_product['ID'] =$row[2];
What I need is to echo a separate 'php-include' depending on this variable, so something like:
<?php include 'includes/size/prod/echo $row[2].php'; ?>
which would display, includes/size/prod/1.php, includes/size/prod/2.php etc
I don't understand how to phrase the 'echo' within the php.
There are a few ways:
//Concatenate array value in double quotes:
<?php include "includes/size/prod/{$row[2]}.php"; ?>
//Concatenate array value outside of quotes:
<?php include "includes/size/prod/".$row[2].".php"; ?>
//or, using single quotes:
<?php include 'includes/size/prod/'.$row[2].'.php'; ?>
//Concatenate variable (not array value) in double quotes:
<?php $page = $row[2]; include "includes/size/prod/$page.php"; ?>
See:
It's very dangerous to include your PHP files with this technic !!
You must prevent this by doing at least a control of included files are PHP
Now to respond to your question:
<?php
// ? $row2 contains more than 1 php file to include ?
// they are seperated by comma ?
$phpToInclude = NULL;
define(TEMPLATE_INCLUDE, 'includes/size/prod/');
if (isset($row[2])) {
$phpToInclude = explode($row[2], ',');
}
if (!is_null($phpToInclude)) {
foreach($phpToInclude as $f) {
$include = sprintf(TEMPLATE_INCLUDE . '%s', $f);
if (is_file($include)) {
// add validator here !!
include ($include);
}
else {
// file not exist, log your error
}
}
}
?>
dear use following working code
$row[2] = '';
$file_name = !empty($row[2])?$row[2]:'default';
$include_file = "includes/size/prod/".$file_name.".php";
include($include_file);
Things get evaluated in double quotes but not in single:
$var = "rajveer gangwar";
echo '$var is musician'; // $s is musician.
echo "$var is musician."; //rajveer gangwar is musician.
So better to use double quotes
Example:
// Get your dynamic file name in a single variable.
$file_name = !empty($row[0]) ? $row[0] : "default_file";
$include_file = "includes/size/prod/$file_name.php";
include($include_file);
You can use the dots for separating a string: So for instance:
$path = 'includes/size/prod/'.$row[2].'.php';
include '$path';
Or you can put it in a variable:
$path = $row[2];
include 'includes/size/prod/$path.php';
Php is able to evaluate a variable within a string.
