HTML Form submission and handling in PHP

i need a help. actually i have a html form as sown below.

<form id="blog" class="" action="blog/save" method="POST">
    <input type="text" id="blog[title]" class="" name="blog[title]" value="" />
    <input type="text" id="blog[tag]" class="" name="blog[tag]" value="" />
    <textarea id="blog[editor]" class="" name="blog[editor]"></textarea>
    <input type="submit" id="blog[save]" name="blog[save]" class="button" value="Save Post" />
    <input type="submit" id="blog[savePub]" name="blog[savePub]" class="button" value="Save & Publish Post" />
</form>

but in the php file i need to check which开发者_开发百科 submit button is clicked blog['save'] or blog['savePub']. and i tried like this

if ($_REQUEST['blog[save]']) {
       echo $_POST['blog[title]'];
} 
else if($_REQUEST['blog[savePub]') {
       echo $_POST['blog[title]'];
}

but i am getting an error Notice: Undefined index: blog[save]

please help me to find a solution for this problem.

Thanks in advance... Wishes and Prayers.. Jaison Justus

try

if (isset($_POST['blog']['savePub']))
   echo $_POST['blog']['editor'];

when you use [ and ] in html form names PHP conveniently transforms them into sub arrays so you'll find your data at $_POST['blog']['title'] and $_POST['blog'][savePub'] etc

Try this,

if (isset($_POST['blog']['save'])) {
       echo $_POST['blog']['title'];
} 
else if(isset($_POST['blog']['savePub'])) {
       echo $_POST['blog']['title'];
}

Try this

if (isset($_POST['blog']['save'])) {
       echo $_POST['blog']['title'];
} 
else{
       echo $_POST['blog']['title'];
}
