Question

i created a buy.html:

<form action="result.php" method="post">
<input type="radio" Name="ptype" />aaa<br/>
<input type="radio" Name="ptype" />bbb<br/>
<input type="submite" value="Submit" />

then i created a result.php

<?php
...
...
$sql="SELECT address, ptype, price FROM property WHERE ????"
?>

“aaa” and “bbb” are the radio buttons value which are a type of “ptype” in property table

so if i select “aaa”, i want to do a query for rows with “aaa” in ptype. how can i do that?

Answer 1

You must set value of input element

<form action="result.php" method="post">
    <input type="radio" Name="ptype" value="a" />aaa<br/>
     <input type="radio" Name="ptype" value="b" />bbb<br/>
     <input type="submit" value="Submit" />
</form>

THEN

<?php
$ptype = $_POST['ptype'];
$sql="SELECT address, ptype, price FROM property WHERE ptype ='" . $ptype . "'";
?>
