Help with IF and ELSE statement confusion

[andrew_biggart]

Ok what I am trying to do is create a script which first checks if the user is logged in, if they are display a comment form if they are not do not display the form. Next once that has been checked I want to check if the user has submitted the form, if they have run the insert mysql statement and if they havnt do nothing.

 

I have messed about with it so much and I can get certain parts working but not others, Please help me get my head around it...

 

Here is what I have.

 

				<?php
				if(isset($_SESSION['myusername'])) {
				echo "
						<form method='post' action='#Profile_comment'>
							<table class='pro_addcomment'>
								<tr>
									<td class='pro_add_h' colspan='3'>Add a profile comment</td>
								</tr>
								<tr>
									<td class='pro_add_text' colspan='2'>
									<textarea name='profilecomment' class='pro_add_input'></textarea>
									</td>
									<td rowspan='2' class='pro_view_pic' valign='top'>
									<img src='../Profile_pics/". $image ."' style='width:50px; height:50px;' />
									</td>
								</tr>
								<tr>
									<td class='pro_add_max'>Max 200 characters</td>
									<td class='pro_add_button'>
									<input class='acc_alerts_accept' name='add_comment' type='submit' value='Add Comment' />
									</td>
								</tr>
							</table>								
						</form>
						";

						if(isset($_POST['add_comment'])){

						include("config.php");

						$Comment_user=$_GET['username'];
						$Comment_sender=$_SESSION['myusername'];
						$Comment_comment=$_POST['profilecomment'];
						$Profile_picture=$_SESSION['myavatar'];

						$sql="INSERT INTO biggartfp9_profile_comments_tempt (Comment_user, Comment_sender, Comment_date, Comment_content, Profile_picture)VALUES('$Comment_user','$Comment_sender',  NOW(),'$Comment_comment', '$Profile_picture')";
						$result=mysql_query($sql);


						if($result){
						header("location:profile.php?username=$Comment_user#Profile_comment");
						}
						else{
						}

				}
				else{
				echo"<h1 class=status_red>Please Login to submit a comment!</h1>";
				}		
			?>

...and I can get certain parts working but not others...

 

Care to share which bits are working and which bits aren't?

Well at the minute im getting a syntax error which I cannot spot, and then i can test it and let you know

[andrew_biggart]

ok sorted the syntax error, but now even when i am logged in it shows the form but also the the you need to be logged in echo. And also the second if statement is not working.

 

Hear is the new code.

 

				<?php
				if(isset($_SESSION['myusername'])) {
				echo "
						<form method='post' action='#Profile_comment'>
							<table class='pro_addcomment'>
								<tr>
									<td class='pro_add_h' colspan='3'>Add a profile comment</td>
								</tr>
								<tr>
									<td class='pro_add_text' colspan='2'>
									<textarea name='profilecomment' class='pro_add_input'></textarea>
									</td>
									<td rowspan='2' class='pro_view_pic' valign='top'>
									<img src='../Profile_pics/". $image ."' style='width:50px; height:50px;' />
									</td>
								</tr>
								<tr>
									<td class='pro_add_max'>Max 200 characters</td>
									<td class='pro_add_button'>
									<input class='acc_alerts_accept' name='add_comment' type='submit' value='Add Comment' />
									</td>
								</tr>
							</table>								
						</form>
						";

						if(isset($_POST['add_comment'])){

						include("config.php");

						$Comment_user=$_GET['username'];
						$Comment_sender=$_SESSION['myusername'];
						$Comment_comment=$_POST['profilecomment'];
						$Profile_picture=$_SESSION['myavatar'];

						$sql="INSERT INTO biggartfp9_profile_comments_tempt (Comment_user, Comment_sender, Comment_date, Comment_content, Profile_picture)VALUES('$Comment_user','$Comment_sender',  NOW(),'$Comment_comment', '$Profile_picture')";
						$result=mysql_query($sql);


						if($result){
						header("location:profile.php?username=$Comment_user#Profile_comment");
						}
						else{
						}

				}
				else{
				echo"<h1 class=status_red>Please Login to submit a comment!</h1>";
				}

Try this.

also in Header(); use a full path to url.

 

				<?php
				if(isset($_SESSION['myusername'])) {
				echo "
						<form method='post' action='#Profile_comment'>
							<table class='pro_addcomment'>
								<tr>
									<td class='pro_add_h' colspan='3'>Add a profile comment</td>
								</tr>
								<tr>
									<td class='pro_add_text' colspan='2'>
									<textarea name='profilecomment' class='pro_add_input'></textarea>
									</td>
									<td rowspan='2' class='pro_view_pic' valign='top'>
									<img src='../Profile_pics/".$image."' style='width:50px; height:50px;' />
									</td>
								</tr>
								<tr>
									<td class='pro_add_max'>Max 200 characters</td>
									<td class='pro_add_button'>
									<input class='acc_alerts_accept' name='add_comment' type='submit' value='Add Comment' />
									</td>
								</tr>
							</table>								
						</form>
						";

						if(isset($_POST['add_comment'])){

						include("config.php");

						$Comment_user=$_GET['username'];
						$Comment_sender=$_SESSION['myusername'];
						$Comment_comment=$_POST['profilecomment'];
						$Profile_picture=$_SESSION['myavatar'];

						$sql="INSERT INTO biggartfp9_profile_comments_tempt (Comment_user, Comment_sender, Comment_date, Comment_content, Profile_picture)VALUES('$Comment_user','$Comment_sender',  NOW(),'$Comment_comment', '$Profile_picture')";
						$result=mysql_query($sql);


						if($result){
						header("Location: profile.php?username=$Comment_user#Profile_comment");
						}
						else{
						}

				}
				else{
				echo"<h1 class=status_red>Please Login to submit a comment!</h1>";
