[Resolved] Passing information from HTML to PHP

JJ123

<select name="Search">
<option value="Ticket">Ticket Number
<option value="Name">Name
</select>
<br><br>

<?PHP

//$Select = value;
echo $Search;

I have this code and in the php section I need a series of if statements based on the selection from the drop down box that is in the html section of my page.

I don't know how to capture this information. Can someone help?

Thanks,

dalecosp

<select name="Search"> 
<option>Ticket Number 
<option>Name 
</select> 
<br><br>

$search=$_GET['search'];  // OR POST, depends on form

/* EDIT: no, it doesn't, not really, what a kook I am late */
/* at night... forms POST,  URL's GET  apples !=oranges */

switch ($search) {
   case "Ticket Number" :
         //some function or whatever
        break;
   case "Name" :
         //some function or whatever
        break;

Thank you - that helps a lot.

Now I am wondering how to get the code to be implemented when the choice in the drop down is selected. For example, if a user selects Name from the drop down, I want a certain action to occur. Is there a function similar to 'on change'?

Plus I am using the following line at the beginning of the page:
<FORM method="POST" action="ticket.php">
So from what you are saying I have to change the line you are giving me to:
$search=$_POST['search'];?? Just checking.

Also if I wanted to use GET as you put, what would the Form method be set at?

Thank you,

You're welcome, and you are reading me quite correctly.

As for GET, it wouldn't be a form method, I guess, just a "method" of handling input.

http://url.com?search="golfshoes"

...as an example.

Received thusly in "handler.php"

$search=$_GET['search'];
if ($search=="golfshoes") {
   echo "what size, Tiger?";
   }

As for 'on change' --- you'll need to code it that way (Javascript) if you want it to occur on user action, as PHP is server-side all the way....

Is it common to use PHP and Javascript in the same page? Or does it get messy?

Hmm, I remember posting a reply earlier, but don't see it. Box didn't crash, wonder what happened?

Common...yes, most likely. They handle different sides of the transaction. Messy? Probably depends on the coder.

Consider:

if (!$_COOKIE['mysite']) {
   echo "<script language=\"javascript\" type=\"text/javascript\">";
   echo "alert(\"Welcome, new user!\")";
   echo "</script>";
   }

don't forget you can use:

if (!$_COOKIE['mysite']) {

   echo <<< EOL
    <script language="javascript" type="text/javascript">
        alert("Welcome, new user!") 
    </script>
EOL
}

<?php
if (!$_COOKIE['mysite']) {
?>
<script language="javascript" type="text/javascript">
alert("Welcome, new user!") 
</script>
<?php
}
