[RESOLVED] Form Submission Problem

[infected_toe]

Form works fine if the two fields are completed and Upload Photo button is clicked. It fails if user presses Enter after entering a caption.

Heh? Can I keep the form from being submitted by pressing Enter and require the Upload Photo button to be clicked? (Probably overlooking something simple.)

if (isset($addphoto))
	{
	$division=$_GET['division'];
	echo "<form method=\"post\" action=\"$_SERVER[PHP_SELF]\" enctype=\"multipart/form-data\"> \n"; 
	echo "<table width=\"100%\" cellspacing=\"0\" cellpadding=\"3\" border=\"1\" bordercolor=black>";
	echo "<tr valign=\"top\" bgcolor=\"#ffc0c0\"><td colspan=\"4\" align=\"center\"><h2>Add a Photo</h2></td></tr>";
	echo "<tr valign=\"top\" bgcolor=\"#ffffff\"><td><b>Filename: </b></td><td><input type=\"file\" name=\"uploadedfile\" size=\"50\"></td></tr>";
	echo "<tr valign=\"top\" bgcolor=\"#ffffff\"><td><b>Caption: </b></td><td><input type=\"text\" name=\"hpg_caption\" value=\"$hpg_caption\" size=\"50\" maxlength=\"50\"></td></tr>";
	echo "<input type=\"hidden\" name=\"hpg_division\" value=\"$division\">";
	echo "<input type=\"hidden\" name=\"hpg_username\" value=\"$c_fname $c_lname\">";
	echo "<tr><td align=\"center\"><input type=\"submit\" name=\"savephoto\" value=\"Upload Now\"></td><td>Please be patient for file to upload.</td></tr></table></form>";
	}

What do you mean it "fails" ? You mean it doesn't submit all of the data your script is looking for, and therefore fails to do what it's supposed to?

Why not test if the data has been sent before processing the form? Example:

if(empty($_POST['uploadedfile']) || empty($_POST['hpg_caption'])) {
    echo 'Error: Please fill in all fields and then submit the form.';
}

I say it fails because it doesn't run the savephoto process when the form is return on itself.

The code below runs if the Upload Photos is clicked but not if Enter is pressed after the caption field.

if (isset($savephoto))
	{
	$division="$_POST[hpg_division]";
	$hpg_caption="$_POST[hpg_caption]";
	$uploadedfile="$_POST[uploadedfile]";
	$hpg_username="$_POST[hpg_username]";

echo "Division: $division<p>";
echo "Caption: $hpg_caption<p>";
echo "uploadedfile: $uploadedfile<p>";
echo "Username: $hpg_username<p>";
die();

uploading script;
adding to db script;
etc. etc. etc.

Edit:
Got it working by placing ?savephoto in here:

echo "<form method=\"post\" action=\"$_SERVER[PHP_SELF]?savephoto\" enctype=\"multipart/form-data\"> \n";

Thanks
