Fields in form should be remembered

[toplisek]

I have code for form:

<form action="<?php echo $PHP_SELF; ?>" method="post" >

Problem is if user made mistake and goes back in browser or form shows error message in the same window. I would like that users input is remebered not empty fields if e.g. there is error message. Do you know how to do it? Need help

Here is a function that is E_ALL safe so you don't need to keep repeating code:

<?php
function sticky($key, $type = NULL, $value = NULL)
{
   if(empty($_POST[$key])) return FALSE;
   if($type != ('radio' or 'checkbox' or 'option')) return $_POST[$key];
   if(($type == 'radio') and ($value == $_POST[$key])) return ' checked="checked"';
   if(($type == 'checkbox') and (($value == $_POST[$key]) or (is_array($_POST[$key])
   and in_array($value, $_POST[$key])))) return ' checked="checked"';
   if(($type == 'option') and  ($value == $_POST[$key])) return ' selected="selected"';
   return FALSE;
}
?>

<?php
// the following is solely for demonstration purposes
?>
<form action="<?php echo $PHP_SELF; ?>" method="post">
<input type="text" name="field1" value="<?php echo sticky('field1'); ?>"><br><br>
<input type="radio" name="field2" value="yes"<?php echo sticky('field2', 'radio', 'yes'); ?>>Yes &nbsp;&nbsp;&nbsp;
<input type="radio" name="field2" value="no"<?php echo sticky('field2', 'radio', 'no'); ?>>No<br><br>
<input type="checkbox" name="field3[]" value="optionA"<?php echo sticky('field3', 'checkbox', 'optionA'); ?>>Option A &nbsp;&nbsp;&nbsp;
<input type="checkbox" name="field3[]" value="optionB"<?php echo sticky('field3', 'checkbox', 'optionB'); ?>>Option B<br><br>
<select name="field4" size="1">
<option value="A"<?php echo sticky('field4', 'option', 'A'); ?>>A</option>
<option value="B"<?php echo sticky('field4', 'option', 'B'); ?>>B</option>
</select><br><br>
<input type="submit" name="submit" value="Roll">
</form>

Hi Bokeh,
your code works perfectly. I have problem just with fileds if they are as following code:

<textarea name="bodycon1" class="inputfield"  rows="10" cols="50" onfocus="activatefield(this);" onblur="deactivatefield(this)"
    value="<?php echo sticky('bodycon1'); ?>"></textarea></TD>

Do you know how to fix this or I have something wrong in my code?

[bathurst_guy]

you have something wrong with your code

<textarea name="bodycon1" class="inputfield"  rows="10" cols="50" onfocus="activatefield(this);" onblur="deactivatefield(this)"><?php echo sticky('bodycon1'); ?></textarea></TD>

<textarea name="bodycon1" class="inputfield"  rows="10" cols="50" onfocus="activatefield(this);" onblur="deactivatefield(this)"><?php echo sticky('bodycon1'); ?></textarea></TD>

It was shown just sample and part of script, because other possibilities work.Textarea will not be remembered. I do not know what is wrong.

There is wrong </TD>, other is correct and it works.

Bathurst Guy has fixed it for you

textareas dont have a "Value" feild. The text to be inserted is like thi
<textarea>text text</textarea>


The last code supplied will work for you.

[bokeh]

Well if you actually had taken the time to look at Bathhurst's post you would understand.

<?php ?>

<textarea><?php echo sticky('bodycon1'); ?></textarea>

And why are you using tables around form elements.

[bathurst_guy]

Maybe I wasn't clear with my post.
You asked "Do you know how to fix this or I have something wrong in my code?" So I answered "you have something wrong with your code" and then provided the solution.

Thank you. Now I understand. I have fixed as bathurst_guy told me. Thanks for all posts.
