question about displaying select and radio button

[runway27]

hi

i have registration form where user selects from a drop down to select their area code apart from filling other details in the form. in the next page which is a confirmation page i would like to display the select option that a user choose in the first page i am able to display this using a textfield however i would like to display using the select drop down.

following is the code for both select and radio button that i have used.

1. Select tag

$pcontactnumber = addslashes($_POST["pcontactnumber"]);

<select name="pcontactnumber">
<option value="09"> <?php if $pcontactnumber == "09" echo "selected" ?>09</option>
<option value="07"> <?php if $pcontactnumber == "07" echo "selected" ?>07</option>
</select>

2. radio button
<script language="javascript">

var m = document.confirmregistrationform.gender.Male.check ed;
var f = document.confirmregistrationform.gender.Female.che cked;
</script>

echo "<input type =\"radio\" name=\"gender\" value=\"Male\" if($gender=='Male') m // Male";
echo "<input type =\"radio\" name=\"gender\" value=\"Female\" if($gender=='Female') f // Female";

2. radio button
echo "<input type =\"radio\" name=\"gender\" value=\"Male\" if($gender=='Male') {gender.checked}>Male";
echo "<input type =\"radio\" name=\"gender\" value=\"Female\" if($gender=='Female') {gender.checked}>Female";


please correct the code and provide the correct syntax to display the information for select tag and radio button in the confirmation page using php


also i have another question, how can i pass a variable to a php file when a user clicks on a link without submitting a form
Ex:
Please choose your user name <input type="text" name="username"> <a href="checkusername.php">check availability</a>

i have tried document.myform.submit(); onclick event for the <a> tag however it does not work

please advice.

thanks

is the select tag that you give us is in confirmation page?
if yes, you must get the variabel that passing from registration form, i think it can be like this..

in registration form :
<select name="pcontactnumber">
<option value="09"> 09</option>
<option value="07"> 07</option>
</select>

in confirmation page :
<select name="pcontactnumber">
<?
$pcontnumber = $_POST["pcontactnumber"];
?>
<option value="09" <? if ($pcontnumber == "09") echo "selected" ?> > 09 </option>
<option value="07" <? if ($pcontnumber == "07") echo "selected" ?> > 07 </option>
</select>

u can try like that.
for second quest. u can use this :
<a href="something_page.php?variablename=variablevalu e">link</a>

exp :
<a href="check.php?id=2">link</a>

be sure "=" and "?" sign cant have a space in left and right... check.php?id=2
