PHP - Php Oop Coding, Please Comment.
Hi,
I'm trying to improve my coding and would appreciate if someone could comment and alter my code. I dont know what would work best, named placeholders or question mark placeholders. Place the variables in a array first and then do the binding. Im looking also for solutions regarding record update using place holders. Thanks
$idnrr = 1;
$users = DB::getInstance()->query("SELECT * FROM users WHERE id = :id1", array(':id1' => $idnrr));
if ($users->count()) {
foreach ($users->results() as $result) {
echo $result->name . "<br />";
}
}
public function query($sql, $params) {
$this->_error = false;
if ($this->_query = $this->_pdo->prepare($sql)) {
$x = 1;
if ($this->_query->execute($params)) {
$this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ);
$this->_count = $this->_query->rowCount();
} else {
$this->_error = true;
}
}
return $this;

Since my last post about the website I was working on, I've figured out what I was asking. But now, I've run into another problem... Once I have a functional form on my website where a user inputs data and presses submit, how do I go about getting it to remain posted where directed? So if the user types his first and last name and presses submit, how do I get their input to remain posted on the page, much like a guestbook? I'm a newbie at this stuff, but it's a must for mine and my partner's website. Thanks again! PS... I have the code for the form all typed out and it works, it just displays the data with $echo rather than posting it permanantly. I've got a comment box that connects to a MySQL database. I've got this error message here when I use the PHP include function to call on this script on my main page http://www.inkzoid.com/index.php ... <?php // calling session_start() the function which starts our authentication session session_start(); // connecting to mysql server $l = mysql_connect ( "999.999.999.999" , "inkzoid" , "999) or die("Error connecting:<BR><BR>".mysql_error()); mysql_select_db( "inkzoid" ) or die("Error getting db:<BR><BR>".mysql_error()); // defining getShouts() which is our function that gets all of our shouts function getShouts() { echo '<div align="center"> <table width="150" border="0" cellspacing="0" cellpadding="0"> <tr> <td> '; $query = mysql_query("SELECT * FROM shouts ORDER BY id DESC LIMIT 10") or die(mysql_error()); while ($row = mysql_fetch_array($query) ) { $name = stripslashes($row['Name']); $contact = stripslashes($row['Contact']); $shout = stripslashes($row['Shout']); if(empty($contact)) { echo '<p><span class="author">'.$name.'</span> - <span class="shout">'.$shout.'</span></p>'; } else { echo '<p><span class="author"><a href="'.$contact.'" target="_blank">'.$name.'</a></span> - <span class="shout">'.$shout.'</span></p>'; } // if empty contact } // while row mysqlfetcharray query echo '<br><br>'; echo ' </td> </tr> <tr> <td height="10"> </td> <form name="shout" method="post" action="shout.php"> <div align="center"> <input name="name" type="text" id="name" value="Name" size="25" maxlength="10"><br> <input name="contact" type="text" id="contact" value="http://" size="25"><br> <input name="message" type="text" id="message" value="Message" size="25"><br> <input name="shout" type="submit" id="shout" value="Shout!"> </div> </form> </td> </tr> </table> </div> '; } // function getshouts // our processing if control statement if ( isset ( $_POST['shout'] ) ) { $name = addslashes($_POST['name']); $contact = addslashes($_POST['contact']); $message = $_POST['message']; if ( ( isset($name) ) && ( isset($message) ) ) { // getting smilie list $smilies = mysql_query("SELECT * FROM smilies") or die(mysql_error()); while($get = mysql_fetch_array ($smilies)) { $alt = $get['Alt']; $smilie = $get['URL']; $message = str_replace( $get['Symbol'] , '<img src="smilies/'.$smilie.'" border="0" width="15" height="15" alt="'.$alt.'">' , $message); $themessage = addslashes($message); // replacing all smilies } mysql_query("INSERT INTO shouts (Name, Contact, Shout) VALUES ( '$name' , '$contact' , '$message' )") or die(mysql_error()); $_SESSION['has_posted'] = 'yes'; header("Location: shout.php"); // if required fields aren't empty, process into database } else { echo '<script>alert("Some fields were not filled out!");</script>'; header("Location: shout.php"); // if required fields were left empty, show an error dialog } }/* else { echo '<script>alert("Please follow the form to this page.");</script>'; header("Location: shout.php"); // if they weren't even referred from the form, show error dialog and redirect } // if isset post shout /* STARTING THE MAIN SCRIPT NOW */ // starting the table //displaying the shouts getShouts(); mysql_close($l); ?> I was told that I should put ob_start(); at the top of my page and ob_end_clear(); at the end of my page, but should that code go on the shout.php file or my index.php file (index.php is where I want my comment box to go)? I was using session_start(); but I got some error messsages about headers already being sent because I had originally used the php include function at the top of index.php to include shout.php. After reading up on it I found out that the error was caused by not having session_start(); being the first line of code. So my problem was that I wanted the comment box to be somewhere other than at the top of the page. Not sure how to move it. Anyways I'm pretty confused right now and if someone could give me some advice it would be appreciated. I have a comment form that I have created. It gets the id from the database and prints out the data that goes with that id, but what it also does is prints out the information into the form. I want a blank form so that the user can add a comment to the record. Any ideas? This the code for the form: Code: [Select] <form method="post" action="pv.php?id=<?php echo $row['ID']?>&action=<?php echo $form_action ?>"> <fieldset> <legend></legend> <p> <label for="cname">Date Of Birth</label> * <input id="cname" name="dateofbirth" class="required date" value="<?php echo $row['Date_Of_Birth']?>" /> (eg 1978.11.11) </p> <p> <label for="cgender">Gender</label> * <input type="radio" name="gender" value="Male" <?php if($row['Gender']=='male'){echo 'checked';}?>/> Male <input type="radio" name="gender" value="Female" <?php if($row['Gender']=='female'){echo 'checked';}?>/> Female </td> </p> <p> <label for="curl">Title</label> * <select name="title" id="title" class="required"> <option value="">Please Select</option> <option value="Mr" <?php if($row['Title']=='Mr'){echo 'selected';}?>>Mr</option> <option value="Ms" <?php if($row['Title']=='Ms'){echo 'selected';}?>>Ms</option> <option value="Mrs" <?php if($row['Title']=='Mrs'){echo 'selected';}?>>Mrs</option> <option value="Miss" <?php if($row['Title']=='Miss'){echo 'selected';}?>>Miss</option> <option value="Other" <?php if($row['Title']=='Other'){echo 'selected';}?>>Other</option> </select> </p> <p> <label for="ccomment">First Name</label> * <input type="text" name="firstname" value="<?php echo $row['First_Name']?>" maxlength="50" /> </p> <p> <label for="cemail">Last Name</label> * <input id="cemail" type="text" name="lastname" value="<?php echo $row['Last_Name']?>" maxlength="75" /> </p> <p> <label for="ccomment">Address 1</label>* <input type="text" name="address1" value="<?php echo $row['Address_Line_1']?>" maxlength="50" /> </p> <p> <label for="ccomment">Address 2</label> <input type="text" name="address2" value="<?php echo $row['Address_Line_2']?>" maxlength="50" /> </p> <p> <label for="ccomment">City</label>* <input type="text" name="city" value="<?php echo $row['City']?>" maxlength="50" /> </p> <p> <label for="ccomment">Postcode</label>* <input type="text" name="postcode" value="<?php echo $row['Postcode']?>" maxlength= "10" /> (eg LE5 5QE) </p> <p> <label for="ccomment">Contact No</label>* <input type="text" name="contactno" value="<?php echo $row['Contact_No']?>" maxlength= "12" /> (eg 077448825723) </p> <p> <label for="ccomment">Email</label>* <input type="text" name="email" value="<?php echo $row['Email']?>" maxlength= "40"/> (eg info@example.com) </p> <p> <label for="ccomment">Comment</label> <textarea rows="10" cols="30" name="note" maxlength= "500"><?php echo $row['Additional_Comment']?></textarea> </p> <p> <input class="submit" type="submit" value="Submit"/> </p> <p> <a href='pv.php'>Main Page</a> </p> </fieldset> This is the code for printing out the data on the page: Code: [Select] if($_GET['action']=='comment'){ $form_action = 'comment_ok'; $id=$_GET['id']; $result = mysql_query("SELECT * FROM project_data WHERE id='$id'"); $row = mysql_fetch_array($result); echo'<b>'; echo $row['Date_Of_Birth']; echo '  '; echo $row['Gender']; echo '  '; echo $row['Title']; echo '  '; echo $row['First_Name']; echo '  '; echo $row['Last_Name']; echo '  '; echo $row['Address_Line_1']; echo '  '; echo $row['Address_Line_2']; echo '  '; echo $row['City']; echo '  '; echo $row['Postcode']; echo '  '; echo $row['Contact_No']; echo '  '; echo $row['Email']; echo '  '; echo $row['Additional_Comment']; echo '</b>'; } and a snippet of the code I am using to send the id to the form: Code: [Select] echo "<td><a href='pv.php?action=edit&id=" . $row['ID']."'>Edit</a>  <a href='pv.php?action=delete_ok&id=" . $row['ID']."'>Delete</a>  <a href='pv.php?action=comment&id=" . $row['ID']."'>Comment</a></td>"; echo "</tr>"; I dont no if this should even go here but here it goes. I created a blog were each blog post is veiwed on the same page in regards to the id passed to it (as standard). What i really need to do is incorporate the facebook comment box onto the page but... it only relates to the document itself rather than it's dynamic content. Hi everyone, I have a like button on repeating regions that is used for keeping a record of votes on comments. People click it an it adds 1 to the votes column total. It works just fine. Problem is i only want to a allow a user one vote per comment only. can vote on other comments as well, but again, only one vote per day per comment. i wouldn't know where to start. Would i use a cookie or record an ip? switch ($_REQUEST['action']) { case 'likeit'; foreach($_REQUEST as $key=>$value){ $$key = $value; } $votes = $_GET['votes']; $total = ($votes + 1); $sql = mysql_query("UPDATE quotes SET votes = '$total' WHERE quoteid = '$quoteid'"); break; } Good Afternoon everyone. I am having some problems in getting a script I found on a forum to work, I have tried contacting the original author but with no joy. Basically its a php/ajax comment system, however I am getting these errors Code: [Select] Notice: Undefined index: type in C:\wamp\www\buy2earn\viewm.php on line 93 Notice: Undefined index: type in C:\wamp\www\buy2earn\viewm.php on line 105 Here is the portion of code that I am working on, I don't understand what $_post['type'] is meant to come from? I guess its basically if the form has been submitted, but if I change the values tp 'submit' I still get the same result, just with the message submit is undefined instead! <?php $date=date("Y-m-d"); $username = $_SESSION['username']; if($_POST['type'] == "addcomment") { $username = mysql_real_escape_string($_POST['username']); $comment = mysql_real_escape_string($_POST['comment']); if($username == "" || $comment == "") { die("<p><font color='red'>Error: Please include a message.</font></p>"); } $q1 = mysql_query("INSERT INTO 'comments' ('c_id', 'm_id', 'username', 'date', 'comment') VALUES ('', '$m_id', '$username', '$date', '$comment')") or die("<p>Mysql Error: <b>".mysql_error()."</b></p>"); echo "<p><font color='green'>Comment added successfully.</font></p>"; } elseif($_POST['type'] == "getcomments") { $q1 = mysql_query("SELECT * FROM 'comments'"); $n1 = mysql_num_rows($q1); if($n1 == 0) { die("<p><font color='red'>No comments were found.</font></p>"); } echo "<table border=1>"; echo "<tr><td><b>User</b></td><td><b>Comment</b></td></tr>"; while($r1 = mysql_fetch_assoc($q1)) { $a = $r1['username']; $m = $r1['comment']; echo "<tr><td>$a</td><td>$m</td></tr>"; } echo "</table>"; } else {?> <div style="font-size: 18px;"> <p>Current Comments: </p> <div id="comments"></div> <hr /> <p>Add a comment:</p> <form action="<?php $_SERVER['PHP_SELF'];?>" method="post"> <p>Username: <input type="text" name="username" id="username" /></p> <p>Comment: <textarea name="message" cols="50" rows="10" id="message"></textarea></p> <p><input type="submit" name="submit" value="Add Comment" id="submit" /></p> </form> <div id="return"></div> </div> <?php } ?> Many Thanks for any help Hi, can anyone help show me or tell me where I can find out how I can create a comment box system that will get the members userid/username and post it with the comment when it has been submitted on the page. e.g the way youtube displays comments with the username and then the comment underneath. thanks, i want that when someone post some comment on post that don't insert in table directly before inserting i can check and after approving then insert in table for which what i doo ?any IDea about this Any one no a simple way to create a numbering system for a basic comment system.

Hi all i hope to find cure to my problems here is code of comment link <a href='/blogs/?page=comment&id=".$row['id']."'>Comment</a> here is code of whole comment page http://paste.php.lv/4c30d2286cdd7334d856ce966abc618f?lang=php And here is Pictures what's is going on on website.... Here is my main issue there are 3 comment's and they all well make such mess .... and if there aren't any comment's have such issue .... Ok, so I want to make a comment spam filter for my site. I know the basic logic, but have yet to figure out how to write the functions. I have a database table called comments that has a column called "time", which contains a unix timestamp value of when it was posted. Basically what I want to do is this: When a user tries to post a comment, the script determines with a database query if they have posted a comment in the last 120 seconds. So basically I have to find the current time, and the time it was 120 seconds before the current time. Then I have to find any comments posted by the user that were made after the 120 second mark. My database query should then look something like this, right? Code: [Select] $query = mysql_query("SELECT * FROM comments WHERE author = ".$_SESSION['id']." AND time > '".$120secondsago"'"); Please correct me if my logic is wrong, which it very well may be, but how would I find the unix timestamp code from 120 seconds before the current time? Note that 120 seconds is just an example and also that I have not worked with dates in mysql very often. $query = mysql_query("SELECT * FROM comments WHERE author = ".$_SESSION['id']." AND time Hi guys I'm trying to modify the following script so that only registered users can post comments. Can you guys help please thanks? <?php require_once("admin_common.php"); session_start(); if(is_numeric($_REQUEST['id'])){ $imageid = $_REQUEST['id']; }else{ header("Location: http://mysite.net/"); } if($_POST['submit']){ if($_POST['username']==''){ $err = "You must log in."; }elseif($_POST['thecomment']==''){ $err = "You have to enter a comment."; }else{ $name = strip_tags($_POST['thename']); $themessage = strip_tags($_POST['thecomment']); $ezdb->get_results("INSERT INTO user_comments (id,date_added, posted_by, message, image_id) VALUE ('','".time()."','".$name."','".$themessage."','".$imageid."')"); $err = "Thank you for your comment."; } } if($err){ $err = '<span style="color:#FF0000;">'.$err.'</span>'; } /* Update table `iid_ip`.

I'm working on adding a threaded comment system to a website. The comments will be in reply to posts which are part of a post table. The comment table contains an auto incremented ID, a ThreadID that references the post its replying to and a CommentID that references which comment its replying to if it is a reply to a comment and is null if its a reply directly to the post. It also contains the comment obviously. I can get all the comments for a post and push each comment object into an array and return it to be displayed. What I'm stuck on though is having the comments nested. Any idea's I've came up with fall short of being able to be n level trees. I'm sure the answer is something to do with recursion but I can't think of how it would be implemented in this case. Any help or pointers would be great. I'm reading around but I thought I'd stop in here and ask as well. Thanks in advance. |
