php - Save color using cookies -


hello want save cookie color input , if user refresh page color saved , ready next use.cookies must set 1 hour , if expired cookies deleted.sorry english , help

<table> <form action='' method='post'>     <tr><td><label>url adresa: </label></td><td><input type='text' placeholder='napr.google.com' name='url' /></td></tr>     <tr><td><label>titulek: </label></td><td><input type='text' placeholder='napr.google' name='title' /></td></tr>     <tr><td><label>vyberte barvu: </label></td><td><input type='color' name='color' /></td></tr>     <tr><td><label>otevřít v novém okně </label></td><td><input type='checkbox' name='window' />     <tr><td></td><td><input type='submit' name='submit' /></td></tr> </form> 

<?php  if (isset($_post['submit'])) {        if (!empty($_post['url']))      {         if (!empty($_post['title']))         {             $url = $_post['url'];             $title = $_post['title'];             $color = $_post['color'];             $explode1 = explode("/",$url);             $explode2 = explode(".",$explode1[2]);             setcookie("color", $color, time() + 3600, '/');             if (isset($_post['window']))              {                 setcookie("window", $_post['window'], time()+3600, '/');                 echo "<a style='color:" . $_cookie['color'] . "' href=" . $url . " target='_blank'>" . $explode2[1] . "." . $explode2[2] . "</a>";             } elseif (isset($_cookie['window'])) {                 echo "<a style='color:" . $_cookie['color'] . "' href=" . $url . " target='_blank'>" . $explode2[1] . "." . $explode2[2] . "</a>";             } else {                 echo "<a style='color:" . $_cookie['color'] . "' href=" . $url . ">" . $explode2[1] . "." . $explode2[2] . "</a>";             }         }     } }

?>

you never save $color cookie:

if (isset($_post['window'])) {   setcookie("window", $color, time() + 3600, '/');   echo "<a style='color:" . $color . "' href=" . $url . " target='_blank'>" . $explode2[1] . "." . $explode2[2] . "</a>"; }

or if $color needs saved separately:

setcookie("color", $color, time() + 3600, '/');

personally, save session so:

session_start(); $_session['color'] = $color;

hope helps. edit:

if (isset($_post['submit']) && (!empty($_post['url']) && (!empty($_post['title'])) {   $url = $_post['url'];   $title = $_post['title'];   $color = (($_post['color'] == $_cookie['color'])?$_cookie['color']:$_post['color']);   $explode1 = explode("/",$url);   $explode2 = explode(".",$explode1[2]);   setcookie("color", $color, time() + 3600, '/');   if (isset($_post['window'])) {     setcookie("window", $_post['window'], time()+3600, '/');     echo "<a style='color: $color' href='$url' target='_blank'>$explode2[1]}.{$explode2[2]}</a>";   } else {     echo "<a style='color: $color' href='$url'>{$explode2[1]}.{$explode2[2]}</a>";   } }
