Form problem Tks Guys

[gokeeffe]

Here’s my problem I have a three step registration phase where the user will fill in text boxes and drop downs for the process.

My question is if a user would like to change some of the information after they see the results in the confirmation page what is the best way to do this.

At present I am thinking getting the user to click back to the page they want to change and then enter the new info.

The problem I am having with this method is that the fields appear blank when you go back. How can I keep these values on the forms until the submit button is actually pressed.

Here is a sample of some of the code in my forms

<tr>
<td colspan="2" class="labelcell"><label for = "town_region_name">Town/Region</label></td>
<td colspan="2" class="fieldcell2"><input type="text" name="town_region_name" size="20" maxlength="20"
value="<?php if(isset($_POST['town_region_name'])) echo stripslashes($_POST['town_region_name']);?>"/>
</td>
</tr>

Hope someone can help.

Much appreciated.

I am using sessions to pass data but how to i pass it to the form can you show me with my code how to do it.

 

[vbkris]

//The Page where you enter the data
<?
session_start();
?>
<tr>
<td colspan="2" class="labelcell"><label for = "town_region_name">Town/Region</label></td>
<td colspan="2" class="fieldcell2"><input type="text" name="town_region_name" size="20" maxlength="20"
value="<?php if(isset($_SESSION['town_region_name'])) echo stripslashes($_SESSION['town_region_name']);?>"/>
</td>
</tr>


in the page that collects the data:
<?
session_start();
$town_region_name=$_POST["town_region_name"];
$_SESSION["town_region_name"]=$town_region_name;
?>

in the page after the process is over:
<?
session_start();
session_destroy();
?>


another thing that i wanted to ask:
try this - <a href="javascript:history.back()">Back</a>

if that works then you need not use sessions...

One last question, How can I apply this session magic to my

drop down code. How to I register the sessions using this


echo'<table align="center">';

echo'<tr>
<td colspan="2" class="labelcell"><label for="county_id">Select County:</label></td>';

echo'<td colspan="2" class="fieldcell2">

<select name="county_id">';

$query_result = mysql_query ('SELECT * FROM counties ORDER BY county_id');

while ($row = mysql_fetch_array ($query_result, MYSQL_NUM))

{
echo "<option value=\"$row[0]\">$row[1]</option>\n";
}
echo'</select></td>';

echo'</tr>';


mysql_close();

 

[vbkris]

i dont get you, u can capture the value in a session variable like any textbox's value...

Known is handfull, Unknown is worldfull

 

[gokeeffe]

I mean is it something like this

echo "<option value=\"$_SESSIONrow[0]\">$_SESSIONrow[1] </option>\n";


How do you apply a session to an array that is coming from

a mysql database

 

[vbkris]

while ($row = mysql_fetch_array ($query_result, MYSQL_NUM))

{
$sel="";
if($_SESSION["OptionValueVariable"]==$row[0])
$sel="selected";

echo "<option value=\"$row[0]\" $sel>$row[1]</option>\n";
}
