select form woes

Anon

Hello, I searched this site but could not find an answer to my question.

I have a form displayed using php. The user is to fill out the fields and click submit. If any fields are left blank, the form is redisplayed with error messages for empty fields....and any fields that are filled in are left filled in through the script (using $php_self).

I can get input fields to work ok....that is retain a value on submit.... but the <select>
field is a whole nother ball game. My select field always keeps the value of "select one" even if I have selected Master Card, Visa, etc.
Here is my code for the select field.Please note that this is in a variable called $form_block and $form_block is echoed to the screen. Thanks in advance.

<TD><FONT COLOR=\"red\">*</FONT>&nbsp Credit Card:<br>
<select name=\"cc_type\" size=\"1\">
<option vale=\"\">SELECT ONE
<option value=\"discover\" name=\"discover\">Discover
<option value=\"mastercard\">Master Card
<option value=\"visa\">Visa
</SELECT>
</TD>
</TR>

Same should work as with checkboxes.

I use a var $ischecked and one $notchecked. Depending upon the variable passed to the form, I set $ischecked of $notchecked to "Checked".

both times, just echo the var.

Now with some code:

if ($deelnemer['port_mailen']=="t") {
$port_checked = "checked"; }
else {
$port_not_checked = "checked";
}

Hi Gary,
In a select box, you can determine the default selected option by putting "selected" in the option tag. If there aren't any selected directives in the options tags, the first option will be displayed.

So, the thing to do is not to create your select box statically. Create it using an array.

Then as you create the select box, check to see if the card selected is equal to the option value being echoed. If it is, put the word 'selected' into the option tag.

If $credit is undefined $sel will always be equal to '' and the first option will be displayed.

$cc[]='discover';
$cc[]='visa';
$cc[]='amex';

echo "<select name=credit>";
for($i=0; $i < sizeof($cc); $i++)
{
$sel=($cc[$i] == $credit) ? ' selected' : '';
echo "<option$sel value=$cc[$i]>$cc[$i];
}

matt.

This is a little more complete:

$cc[]='discover';
$cc[]='visa';
$cc[]='amex';

echo "<select name=credit>";

echo "<option value=>Select One";

for($i=0; $i < sizeof($cc); $i++)
{
$sel=($cc[$i] == $credit) ? ' selected' : '';
echo "<option$sel value=$cc[$i]>$cc[$i];
}

echo "</select>";

What about the code for list box content calling from a mysql table?
