PHP and Images

noreencoughlan

Hi Guys

I have a problem, I have a form in HTML which im processing using PHP and i was to be able to give the user a choice in the form to choose a pic and once they submit the form the image (along with text) will be displayed. Anyone have any ideas how i can achieve this??

If it is just that page you wish to show then you can use the user selection of the image name and the text entered into the textbox by obtaining these through $_POST['varname'].

eg.


<form name="form1" method="post" action="action.php">
<input type="text" name="textbox1"></input>
</form>

now action.php


$textentered = $_POST['textbox1'];

If you are perminantly wanting the text and image then you will need to think about the use of sessions or cookies.

Upload all you images on a directory on your web root...like
for example "images",

present a form with radio button next to the pictures. If you want
the form to be dynamic also.. which mean pictures you uploaded to the directory will automatically be added to the form try this

form.php
########################################

<html>
<body>
<form action="display.php method="POST">
Select Picture:<br>
<?php
$d = dir("images/");
while($file = $d->read()) {

if($file != '..' && $file != '.') {
?>
<input type="radio" name="pic" value="<?php echo $file?>">
<img src="images/<?php echo $file ?>"><br>
<?php
}
}
$d->close();
?>
<input type="text" name="somtext">
</form>
</body>
</html>

########################################

display.php
########################################

<html>
<body>
<?php
echo 'sometext: '.$_POST['somtext'];
echo '<img src="images/'.$_POST['pic'].'">';
?>
</body>
</html>

#########################################

make sure that there are only jpegs and gifs on the images directory. Put the two scripts outside of it.

Hope this helps
