PHP Post Working with Fields -


i have simple form:

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd"> <form method="post" action=""> <label>filter zip code: <input maxlength="5" name="zipcode" size="6" type="text" /></label> <label>filter products:  <select name="products">   <option value="">select product</option>   <option value="jewelry">jewelry</option>   <option value="homedecor">home decor</option>   <option value="kitchen">kitchen</option> </select> </label>     <label>filter materials:  <select name="materials">   <option value="">select material</option>   <option value="abs">abs</option>   <option value="gold">gold</option>   <option value="silver">silver</option> </select> </label> <br> <input name="submit" type="submit" value="submit" /> <input name="clear" type="submit" value="clear" /> </form> <?php if (!isset($_post['submit'])){         echo "nothing selected"; } elseif(isset($_post['zipcode']) && ($_post['zipcode'] != "")) { $zip = $_post['zipcode'];         echo "zip data " . $zip; }  elseif(isset($_post['products'])  && ($_post['products'] != "")) { $products = $_post['products'];         echo "products data " . $products; } elseif(isset($_post['materials'])   && ($_post['materials'] != "")) { $materials = $_post['materials'];         echo "materials data " . $materials; } ?>

when posting data take value of first item selected.

i have tried breaking if ... elseif , doing redundant statements.

ie:

elseif(isset($_post['materials']) && ($_post['materials'] != "") || ($_post['products'])  && ($_post['products'] != "") || $_post['zipcode'])  && ($_post['zipcode'] != "")) {

that seems complicated , cannot believe there not easier way.

i have tried using switch ... case same results.

what im looking if 2 filters selected?

what if 3 selected?

how can data post out correctly.

you're checking if "zipcode" posted, , if it's not, if "products" posted, etc...

you should change "else if"s "if" :

<?php if (!isset($_post['submit'])) {     echo "nothing selected"; } else {     if(isset($_post['zipcode']) && ($_post['zipcode'] != ""))     {         $zip = $_post['zipcode'];        echo "zip data " . $zip;     }     if(isset($_post['products']) && ($_post['products'] != ""))     {         $products = $_post['products'];         echo "products data " . $products;     }     if(isset($_post['materials']) && ($_post['materials'] != ""))     {         $materials = $_post['materials'];        echo "materials data " . $materials;     } } ?>

by way, use "if (!empty($_post['myfield']))" instead of checking "isset" , egal empty.

another thing : inputs not supposed inside label, should have :

<label for="myfield">my field :</label> <input name="myfield" ... />
