PHP - Increasing A Number Inside A Variable
how can you increase the page number in the following line until $status returns an empty result?

In above code when i upload title or content within range of 20 words it works properly but when I increase numbers of words till approx. 100 words. It gives an error "Not Connected Events". Not any file is uploaded in database. I set the length of title and content in phpmyadmin is 500 and 1000 and type is varchar respectively. I can't understand where is problem???????? I think it's about something size??????? Help me Anyone??????????????? The Script:
$desired_width = 110;

$file_extension = end($ext); //store extensions in the variable
$new_image_name = md5(uniqid()) . "." . $ext[count($ext) - 1];
$target_path = $target_path . $new_image_name;//set the target path with a new name of image

Hey, sorry that I am posting this darn image upload script again, I have this almost finished and I am not looking to ask more questions when it comes to this script specifically.
With the script above I have that part where the script should store the ID numbers (the auto_increment column of the table) of the image files inside of one array and then the "implode()" function would get used on the array and then the ID numbers would get inserted into the "image_file_id" column of the "thread" table.
As you can see at the above part the script prints the following:
Array ( [0] => 542 )
Array ( [0] => 543 )
Array ( [0] => 544 )
And I am looking to insert into the column of the table the following:
542, 543, 544I thought of re-writing the whole image upload script since this happens inside the for loop, though I thought maybe I could be having this done with the script as it is right now. Any suggestions on how to do this? I have a script that adds points together based upon the placing. This is the actual script: Code: [Select] <? $points = 0; if($place === '1st') {$points = $points + 50;} elseif($place === '2nd') {$points = $points + 45;} elseif($place === '3rd') {$points = $points + 40;} elseif($place === '4th') {$points = $points + 35;} elseif($place === '5th') {$points = $points + 30;} elseif($place === '6th') {$points = $points + 25;} elseif($place === '7th') {$points = $points + 20;} elseif($place === '8th') {$points = $points + 10;} elseif($place === '9th') {$points = $points + 10;} elseif($place === '10th') {$points = $points + 10;} elseif($place === 'CH') {$points = $points + 50;} elseif($place === 'RCH') {$points = $points + 40;} elseif($place === 'TT') {$points = $points + 30;} elseif($place === 'T5') {$points = $points + 30;} elseif($place === 'Champion') {$points = $points + 50;} elseif($place === 'Reserve Champion') {$points = $points + 40;} echo "Total HF Points: $points"; ?>What it *should* do (my friend's script works the same way and it works) it starts at points = 0, than if there is a first place, it adds 50, and so forth until it reaches the end. It is included into a file, in this area: Code: [Select] <div class="tabbertab"> <h2>Records</h2> <? $query92 = "SELECT * FROM THISTABLE WHERE VARIABLE='$id' OR VARIABLE = '$name' ORDER BY ABS(VARIABLE), VARIABLE"; $result92 = mysql_query($query92) or die (mysql_error()); echo "<table class='record'> <tr><th>Show</th> <th>Class</th> <th>Place</th></tr> "; while($row92 = mysql_fetch_array($result92)) { $class = $row92['class']; $place = $row92['place']; $entries = $row92['entries']; $race = $row92['show']; $purse = number_format($row92['purse'],2); echo "<tr><td>$race</td> <td>$class</td> <td>$place</td></tr>"; } ?> <tr><td colspan='3'><div align='right'><? include('includes/points.php'); ?></div></td></tr> </table> </div> This is the code that is relevant. When ended here, it echoes the last place that appears in the results (such as a 5th place echoing 30 points). When I move it to be included in the while loop, it shows Total Points: 50 Total Points: 25 Total Points: 10 (depending on the results displayed on that page). What am I doing wrong? Hi, I'm just starting PHP and I ran into a simple problem (that I can fix), but I just want to understand why my first approach doesn't work. I was testing multiplications and additions and the result I got was unexpected. Here is the code that doesn't work: Code: [Select] <?php $number1 = 5; $number2 = 10; print $number1." multiplied by ".$number2." + 1000 = ".$number1*$number2+1000; ?> Obviously, what I want as a result when I'm displaying the page is: "5 multiplied by 10 + 1000 = 1050" What I get: "1005". That's right, nothing else. On top of getting an erroneous answer, the sentence that's supposed to display right before the equation doesn't display at all. It's even worse if I switch it around like that: Code: [Select] print $number1." multiplied by ".$number2." + 1000 = ".1000+$number1*$number2; I get an error message and nothing displays. The obvious solution works: using a parenthesis at the beginning and at the end of the equation, which I should do regardless, but still, it's bugging me and since I just started learning PHP today, I want to understand how the code is compiled / interpreted so I don't make stupid mistakes like this one. Thanks in advance for the replies. Hi Guyz, I need to check the variable $itemDescription to see if the client has entered a '1' before the item description(example: 1 table) Reason, is the client would like to add sales tax to all NOn-Food related items of 6.25% This is for a local auction house.

Thanks in advance, If I have a for loop with a variable called $counter, how can I use the value of this inside a variable name.

I need to get a variable that defined in an included file inside of a function I've got this Inside file.php I've got the $variable1 and $variable2 defined (they're dynamic/different to each user) include('file.php'); function foo() { GLOBAL $variable1, $variable2; echo $variable1; echo $variable2; } foo(); Yet it outputs nothing? If I Include file.php right inside of the function it works however. Any idea? Im having a problem with getting the quotes correct with this. I can either get the variable to work in the href and img src or in the css. Anyone have any ideas on this. Cuase im really stuck. This allows the $address and $cos to echo in but not the css variables <td><?php echo "<a href='planet_profile.php?planet=$address'> <img src='images/star.jpg' id='$cos' style='position:absolute;' left:'$b_x px;' top:'$b_y px;'></a>"; ?></td> and this allows only the css variables to work <td><?php echo '<a href="planet_profile.php?planet="' . $address .

I have a MySql database with lists of students grouped into classrooms. A typical group is shown in the attached screenshot screenshot.docx. I want to be able to select one or more of the names by using the associated checkbox, and upgrade a student or students into a different group as defined in the radio button list also in the screenshot. I have the rudiments of the file attached, but I have absolutely no idea how I can post the array so that the records are updated. Each student has an individual record with a field name userGroup which holds a string nominated by their classroom teacher, such as "year7", "year 8" and so on while they are in one of the several classrooms, but when they leave school this is recorded in a field named noGroup with a value of 0 or 1. I can post further details as required, but it would be great if someone could help me. I'm trying to build a math game. But I'm having trouble trying to make a variable calculate that contains an operator. Example: $c1_op = "+"; $a1_num_user = $_POST['a1_num']; $e1_num_user = $_POST['e3_num']; $row_1 = $a1_num_user . $c1_op . $e1_num_user; echo "result: " . $row_1; If I now input a 10 and a 2 I will get echo'd out: result: 10+2 It's not calculating. When I don't use any quotation marks then I will get the error "unexpected ;". I need the operator inside a variable, it's the nature of the math game, any idea how I can make it work so it calculates? Hi Everyone, I have built a website utilizing a PHP abstract Webpage class to create the pages. When creating another class that inherits from Webpage class I rewrite abstract functions, etc. where needed. When instantiating an object of the extended classes I pass the constructor the $page_title, $css_file, $meta_data, $keywords, etc., etc.. I am able to pass html markup in a string variable to a class level "Setter" function to populate a "main area" of the website and all works perfectly. However, I have a contact form which I send the "Submit Message" button click to a PHP function that takes care of making sure the form fields are not empty, then sends email and returns a success message back to the calling page, if they are empty, the function returns what fields are empty(required). If the page includes empty and populated fields I want to put the populated fields into session variables so that I may populate the fields when the user is taken back to the page and display to the user the required fields that were empty(this functionality is already within the function). This brings me to my question(see code below for reference): Seeing that I am populating a variable with a string it seems I cannot use an if statement, echo or the like, my IDE gives me errors. How may I insert an if statement where needed to populate the empty form fields? Code: [Select] include('../php_functions/functions.php');//for the chechData() function $error_message = NULL; if(isset($_POST['submit'])) { $error_message = checkData($_POST, 'Renovation & Consulting'); } $main_content = '<form method="post" action=""> <fieldset id="contactform"> <legend>Renovations & Consultations</legend>'. [color=red]//placing a variable here works fine![/color] $error_message .'<div class="row_div"> <div class="label_div"> <label>First Name:</label> </div> <div class="input_div"> <input name="First Name" type="text" maxlength="50" size="50" value="'.[color=red]if(session variable not empty) echo it here;.'"[/color] /> </div> </div> <div class="row_div"> <input name="submit" type="submit" value="Send Message" /> </div> </fieldset> </form>'; Thanks for any and all responses. Chuck The org variable holds the value of the folder name. The problem is that the header is sending out ".$org." and not the actual value of $org. Example output url: http://127.0.0.1/application/".$org."/display/trackingboard.php I want this url if the value is test: http://127.0.0.1/application/test/display/trackingboard.php Thanks! Code: [Select] $org = "test"; header('Location: ../application/".$org."/display/trackingboard.php'); I'm redoing my login script using functions and a basic switch function checking against a $_GET variable (hope you guys know what I'm talking about). What I want to do is create two functions: 1 that displays the login form and 1 that processes the information The form tag would look like this: <form action=\"<?php $_SERVER['PHP_SELF']?>?action=process\" method=\"post\"> </form> Here's my switch statement: Code: [Select] <?php //**************************************** //****************Action****************** //**************************************** switch ($_GET["action"]) { default: case "index": if (!$_SESSION["member"]) { if (!$timeout) { display_form(); } else { echo $timeout_error; } } else { echo "You are already logged in."; } break; case "process": if (!$_SESSION["member"]) { if (!$timeout) { process_form(); } else { echo $timeout_error; } } else { echo "You are already logged in."; } break; } ?> This runs as soon as "login.php" loads. It'll automatically run the commands under case "default" and "index". It'll first check to see if the member's logged in. If not, it'll then check to see if "$timeout" is true ($timeout becomes true if the member has attempted to login 5 times and failed). If not, it'll display the login form, by running "display_form()". Once the form has been filled and submitted, the commands under case "process" will be performed. Again it will first check to see if the member's logged in. If not, it'll check to see if "$timeout" is true. If not, it'll start validating the forms. For the validation, I've created a variable called "$errors_found", and scripted one if statement checking to see if the email and password exist. If so, the variables "$rm_field_un" and "$rm_field_pw" become true, as well as "$errors_found". So, back to submission of the form... If "$errors_found" is true, display the form (when the form is displayed, there will be an if statement within that says "<?php if ($rm_field_un) { echo "Username is wrong."; } ?>", which will be displayed right underneath the username field and label. Same with the password elements). If "$errors_found" is not true, go ahead and register the member. Now, here's where I need help, because I'm really confused as to how to accomplish this. The "display_form()" function will contain a single variable called "$login_form". It will contain a value of the HTML constructed login form, and the function will return the variable. Remember how I stated in the third paragraph up that I will have <php> statements within the form which would display errors if necessary? Well, how do I put those if statements within the HTML, which is contained within the variable? If that last question confuses you, allow me to present you with an instance: Code: [Select] <?php function display_form() { $login_form = " <form name=\"login_form\" method=\"post\" action=\"<?php $_SERVER['PHP_SELF']?>?action=process\"> Username: <input type=\"text\"> <?php if ($rm_field_un) { echo "Username is wrong"; } ?> "; return $login_form; } ?> See what I mean? This code confuses me ALOT. I'm not sure if the <php> tags are needed as it is already contained within existing ones, or what. Can somebody please help me out? Any and all help is much appreciated. =D Hi, How can I check if a variable only has these characters: - number (0-9) - decimal point (.) - positive (+) - negative (-) - dollar ($) I tried is_numeric, but it doesn't like negative values... I need to add the variable value to another variable. I have to accept numbers (including negative and decimals)... ex: 0.1 = TRUE -.1 = TRUE 12 = TRUE 1000.00 = TRUE 12a = FALSE thanks Hi everyone, Like the title says I need to count the amount of 1's in a column but I can't figure out how. Gr and thanx already Ryflex I'm getting the dreaded " Invalid parameter number: number of bound variables does not match number of tokens" error and I've looked at this for days. Here is what my table looks like:
| id | int(4) | NO | PRI | NULL | auto_increment | | user_id | int(4) | NO | | NULL | | | recipient | varchar(30) | NO | | NULL | | | subject | varchar(25) | YES | | NULL | | | cc_email | varchar(30) | YES | | NULL | | | reply | varchar(20) | YES | | NULL | | | location | varchar(50) | YES | | NULL | | | stationery | varchar(40) | YES | | NULL | | | ink_color | varchar(12) | YES | | NULL | | | fontchosen | varchar(30) | YES | | NULL | | | message | varchar(500) | NO | | NULL | | | attachment | varchar(40) | YES | | NULL | | | messageDate | datetime | YES | | NULL |Here are my params:
$params = array(
':user_id' => $userid,
':recipient' => $this->message_vars['recipient'],
':subject' => $this->message_vars['subject'],
':cc_email' => $this->message_vars['cc_email'],
':reply' => $this->message_vars['reply'],
':location' => $this->message_vars['location'],
':stationery' => $this->message_vars['stationery'],
':ink_color' => $this->message_vars['ink_color'],
':fontchosen' => $this->message_vars['fontchosen'],
':message' => $messageInput,
':attachment' => $this->message_vars['attachment'],
':messageDate' => $date );
Here is my sql:
$sql = "INSERT INTO messages (user_id,recipient, subject, cc_email, reply, location,stationery, ink_color, fontchosen, message,attachment) VALUES( $userid, :recipient, :subject, :cc_email, :reply, :location, :stationery, :ink_color, :fontchosen, $messageInput, :attachment, $date);";
And lastly, here is how I am calling it:
$dbh = parent::$dbh;
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING);
if (empty($dbh)) return false;
$stmt = $dbh->prepare($sql);
$stmt->execute($params) or die(print_r($stmt->errorInfo(), true));
if (!$stmt) { print_r($dbh->errorInfo()); }
I know my userid is valid and and the date is set above (I've echo'd these out to make sure). Since the id is auto_increment, I do not put that in my sql (though I've tried that too), nor in my params (tried that too). What am I missing? I feel certain it is something small, but I have spent days checking commas, semi-colons and spelling. Can anyone see what I'm doing wrong?
Trying to figure out how to make it so name is a link to the profile when its echo anyone know how to do this? im at a huge stand still Code: [Select] <?php $sql = "SELECT name FROM users WHERE DATE_SUB(NOW(),INTERVAL 5 MINUTE) <= lastactive ORDER BY id ASC"; $query = mysql_query($sql) or die(mysql_error()); $count = mysql_num_rows($query); $i = 1; while($row = mysql_fetch_object($query)) { $online_name = htmlspecialchars($row->name); echo '<a href="Inbox.php">"'[$goauld]'</a>"'; ?> I am echoing a variable that is an array. I want to change the first part of the variable but don't know how to manipulte names inside the ['brackets'] Code: [Select] echo $row['v1_name']);?> lets say I have a value called $var = v1. How do I substitute that like this: Code: [Select] echo $row[$var.'_name']);?> I know the above doesnt work, but thats what i want it to do :-) |
