Display an image or URL on a specific date
When running your website, sometimes you only want people to see certain images or urls on certain days. This is most likely to happen when you are running an E-commerce website. Let’s say you have certain images or urls you want seen on specific days, this is one way you can do such a task:
Sample text file (dateText.txt):
-
default /logo/logo.gif
-
2007-04-01 /images/logo1.gif
-
2007-06-05 /images/logo2.gif
-
2007-08-10 /images/logo3.gif
-
2007-09-30 /images/logo4.gif
-
2007-12-25 /images/logo5.gif
The function to display the url or image on a specific date:
-
<?php
-
function imagedate(){
-
//http://thedevnet.com/php/snippets/display-an-image-or-url-on-a-specific-date/
-
//get date by opening file
-
$filename = "dateText.txt";
-
$handle = fopen($filename, "r");
-
$contents = fread($handle, filesize($filename));
-
fclose($handle);
-
$array = explode("n",$contents);
-
foreach($array as $item){
-
$arr = explode(" ",$item);
-
if(date("Y-m-d") == $arr[0]){
-
$val = $arr[1];
-
$rtur = TRUE;
-
break;
-
}else{
-
$rtur = FALSE;
-
}
-
}
-
if($rtur){
-
return $val;
-
}else{
-
$def = explode(" ",$array[0]);
-
return $def[1];
-
}
-
}
-
?>
Sample call:
-
<?php
-
include("imagedate.php");
-
$url = imagedate();
-
echo '<a href="'.$url.'">'.$url.'</a>';
-
?>
