Form and results on same page

[holty]

Can i have a form and results on the same php page?

If so how could I do it so - when the user first hits the page they see 2 select boxes, once they submit the results will be shown below with what was the form before having the values that were selected in (not reseted)

Any ideas would be super!

You'd have something like this:

PHP Code:

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="get">
<input type="text" name="searched" value="<?php echo $_GET['searched']; ?>" /> 
<input type="submit" name="submit" value="Search" />
</form>
<?php
if(isset($_GET['submit'])){
  // do search stuff here
}
?>

Thanks Nightfire....


How would you put the value back in if it was a select box rather than a text box field?

Thanks

You'd just need to change it to this.

PHP Code:

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="get">
<input type="checkbox" name="searched" value="1" <?php if($_GET['searched']=="1"){ echo 'checked="checked"';} ?>/><br />
<input type="checkbox" name="searched" value="2" <?php if($_GET['searched'] == "2"){ echo 'checked="checked"';} ?>/><br /> 
<input type="submit" name="submit" value="Search" />
</form>
<?php
if(isset($_GET['submit'])){
  // do search stuff here
}
?>

That might be right, I'm not sure though as I've not used checkboxes for years and forgotten how they work.

Cheers Nightfire - thats really useful but really I was after a select (combo box). The user selects an option from the box and in the search page I would like it to show the option they selected rather than reseting...

cheers for the help - your a star!

[Nightfire]

Doh, I thought I read checkboxes. Sorry, still asleep

It's not really that different from the checkbox example I posted, all you need to do is change the

PHP Code:

<?php if($_GET['searched']=="1"){ echo 'checked="checked"';} ?>

to

<?php if($_GET['Yourselectboxname']=="OPTION VALUE"){ echo 'selected="selected"';} ?>

in each of your options, like

PHP Code:

<select name="searched">
  <option value="1" <?php if($_GET['searched'] == "1"){ echo 'selected="selected"';} ?> />First search</option>
  <option value="2" <?php if($_GET['searched'] == "2"){ echo 'selected="selected"';} ?> />Second search</option>
</select>

Thanks Nightfire....

Got a problem though when I try this..

(I'm trying to display a day select box with 1 to 31)

<?php
for($i=1; $i<=31; $i++){
print("<option value="$i" if($_GET['Day'] == "$i"){ echo 'selected="selected"';}>$i</option>
}
?>

getting parse errors... any ideas?

[Nightfire]

PHP Code:

<?php
for($i=1; $i<=31; $i++){
print("<option value='".$i."'");
if($_GET['Day'] == $i){ 
    echo 'selected="selected"';
}
print(">".$i."</option>");
}
?>

<edit>4th time edited Think I better go back to bed</edit>

Cool - getting 'Undefined index in day.....'

How do I define it? I'm just starting out in the world of php

Don't go back to bed yet!!

the first time the form appears 'Day' wouldn't be set, so you should test with isset or empty

PHP Code:

for($i = 1; $i < 32; $i++)
  {
  echo '<option value="' .$i. '"'
  .((isset($_GET['Day']) && $_GET['Day'] == $i) ? ' selected="selected"' : '').
  '>' .$i. '</option>';
  } 


would be how I'd do it.

Went back to bed and I see okii got my code properly lol, knew it looked weird when I did it, just couldn't realise why it was weird
