So i want to use a count command to check if they already have 3 entries and if so echo a message, but if they have less than 3 entries echo the add a new entry form. This is as far as i have got but ive been trying so long i have confused myself so now i need some help please. <?php include("config_contact.php"); $username=$_SESSION['myusername']; // Retrieve data from database $sql = "SELECT count(Blog_username) as blogcount FROM User_blogT WHERE Blog_user='$username' "; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); if($row['blogcount'] != 3) { echo "You are only allowed to Have 3 entries to your blog at any one time. If you would like to update your blog please delete one of the older entries."; } else{ echo" <form method='post' action='my_profile_blog_submit.php'> <table class='myprofile_blog'> <tr><td class='myprofile_subtext'>Subject :</td><td class='myprofile_blogsub'> <input name='Blog_subject' type='text' style='width: 413px' /></td></tr> <tr><td class='myprofile_subtext' style='width: 120px' valign='top'>Message :</td><td> <textarea name='Blog_message' style='width: 505px; height: 152px'></textarea></td></tr> </table> <br /> <br /> <br /> <table> <tr><td class='myprofile_changesh'>Add a new entry to your Blog ...</td><td class='myprofile_changesh'> </td></tr> <tr><td class='myprofile_subsub'>Add another entry to your blog.

thepip3r Posted April 6, 2009 Share Posted April 6, 2009 did u echo $row['blogcount'] to see if ur getting the results u expect? if you're not, you can either TS that or just run a SELECT SQL query and use mysql_num_rows() to count the number of results... i'd also use if($row['blogcount'] >= 3) { your failure echo statement executes EVERY time unelss the user has submitted 3 entries for that day.

thepip3r Posted April 6, 2009 Share Posted April 6, 2009 well the logic is simple, i don't know what to tell you except change ur code to see what your problem is when the conditional is firing when it's not supposed to be: if($row['blogcount'] >= 3) { echo "rowcount: $row[blogcount] <br>"; echo "You are only allowed to Have 3 entries to your blog at any one time.

andrew_biggart Posted April 6, 2009 Author Share Posted April 6, 2009 If i use this code it echo's that there is 3 blog entries for this user. <?php include("config_contact.php"); $username=$_SESSION['myusername']; // Retrieve data from database $sql = "SELECT count(Blog_username) as blogcount FROM User_blogT WHERE Blog_username='$username' "; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); if($row['blogcount'] > 0) { echo "(" . $row['blogcount'] . ")"; } ?> But using this code the form just always shows up! can anyone see whats wrong? <?php include("config_contact.php"); $username=$_SESSION['myusername']; // Retrieve data from database $sql = "SELECT count(Blog_username) as blogcount FROM User_blogT WHERE Blog_username='$username' "; $result = mysql_query($sql); if($row['blogcount'] > 3){ echo "You are only allowed to Have 3 entries to your blog at any one time.

premiso Posted April 6, 2009 Share Posted April 6, 2009 Each time you post code you revert or change something completely. I do not know where you are getting your logic but it seems as though you keep disregarding any changes made. This is my last attempt to help. <?php include("config_contact.php"); $username=$_SESSION['myusername']; // Retrieve data from database $sql = "SELECT count(Blog_username) as blogcount FROM User_blogT WHERE Blog_username='$username' "; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); // You have to have this for it to even work at all. // if($row['blogcount'] = 3) { // Single equals always amounts to true: if ($row['blogcount'] == 3) { // the double euqal is the comparison and should be used instead. echo "You are only allowed to Have 3 entries to your blog at any one time. If you would like to update your blog please delete one of the older entries."; } else{ echo" <form method='post' action='my_profile_blog_submit.php'> <table class='myprofile_blog'> <tr><td class='myprofile_subtext'>Subject :</td><td class='myprofile_blogsub'> <input name='Blog_subject' type='text' style='width: 413px' /></td></tr> <tr><td class='myprofile_subtext' style='width: 120px' valign='top'>Message :</td><td> <textarea name='Blog_message' style='width: 505px; height: 152px'></textarea></td></tr> </table> <br /> <br /> <br /> <table> <tr><td class='myprofile_changesh'>Add a new entry to your Blog ...</td><td class='myprofile_changesh'> </td></tr> <tr><td class='myprofile_subsub'>Add another entry to your blog.
