PHP - Why Does My For Loop Eliminate The Decimals In A Variable ?
Hi - To me, this doesn't make sense. My Order form uploads product weights in an array . If I echo out those weights they are fine ie 25.25
However, when I try to update the DB for some reason, the for loop strips out all but the first digit, so 25.25 becomes '2' or indeed if I had entered 9999999 it just '9' is entered in to the DB. I have tried using number_format to pre-process the decimals, - but I get an error saying you can not use it in a write format. Many Thanks to anyone who can help with this !! PS - I have abbreviated the below code for clarity: Code: [Select] $weight = $_POST['weight']; for ($i = 0; $i < $numloops ; $i++) { $sql =" UPDATE `confirmedorder` SET orderid = '$orderid[$i]', weight='$weight[$i]',status='finished', ordervalue='$ordervalue' WHERE customerid = $customerid "; $this->db->query($sql); } Similar Tutorialsi have a variable called $cake it needs to have this loop inside it so I can call it out Code: [Select] while( $r = $DB->fetch_row() ){ if ( $r['last_activity'] > (time() - 900) ) $r['status'] = "<span style=float:right;><span class=desc4><b>Online</b></span></span>"; else $r['status'] = "<span style=float:right;><span class=desc4>Offline</span></span>"; $column++; if ($ibforums->member['settings']['2'] or (!$ibforums->member['id'])){ $color = "{$r['color']}"; $colors = explode(",", $color); if ( strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') ){ { $r['color'] = ($r['color']) ?

So basically $html needs to be $html1 on the next loop, $html2 on the next, and so on. Its probably simple, but its late and I'm tired, I can't seem to figure this one out. Here is my unfinished attempt: $htmlnum = 0; $endo = mysql_query("SELECT * FROM endorse WHERE endonum = '$endonum' AND agency = '$agency' ORDER BY ID DESC LIMIT 1"); while($endofetch = mysql_fetch_array($endo)){ $endotype = $endofetch['type']; $htmlnum = $htmlnum++; $p->htmltable($html); } I want to save the results of a loop as a variable ie $output. I have tried encasing the php within quotes but it does not work. Is there a way to save the complete results as a variable? $result = mysql_query("SELECT * FROM $table2 WHERE $db_item_1 OR $db_item_2", $connection); if (!mysql_num_rows($result)) { echo "Error 13424 - not working"; exit(); } while ($row = mysql_fetch_array($result)) { echo "<tr><td scope=\"col\" style=\"font-size: 16px; color: #333333; padding: 10px 8px; border-bottom: 1px solid #919191;\"><div align=\"left\" style=\"font-size: 20px;\">" . $row['date'] . "</div></td> <td scope=\"col\" style=\"font-size: 16px; color: #333333; padding: 10px 8px; border-bottom: 1px solid #919191;\"><div align=\"left\"></div></td> <td scope=\"col\" style=\"font-size: 16px; color: #333333; padding: 10px 8px; border-bottom: 1px solid #919191;\"><div align=\"left\" style=\"font-size: 20px;\">" . $row['title'] . "</div></td> <td scope=\"col\" style=\"font-size: 16px; color: #333333; padding: 10px 8px; border-bottom: 1px solid #919191;\"><div align=\"left\"></div></td> <td scope=\"col\" style=\"font-size: 16px; color: #333333; padding: 10px 8px; border-bottom: 1px solid #919191;\"><div align=\"left\" style=\"font-size: 20px;\">" . $row['cost'] . "</div></td> </tr>"; }echo $complete;() The part I want as one result (ie. $complete) is the result of the while loop. There is always at least one result but sometimes 10 which means that it creates 10 table rows. I need to do it this way as later on in the page I use a pdf converter which does not allow loop checks within it otherwise I would just place it within the converter. I'm trying to take a number of items from a database using a while loop and put the results into a variable so that I can send one email with all the results. I'm having trouble figuring this out though. Can anyone please give me any ideas as to how to make this work? Here's what I've done so far... all it does is result in an email with the first set of results in the while loop, not all of them. Code: [Select] <?php include("conf.inc.php"); $result = mysql_query("SELECT `to`,`from`,`subject`,`message`,`date` FROM allmsgs WHERE reported = 'n' ORDER BY `messid` ASC"); $row = mysql_fetch_row($result); $cdate = date('m-d-Y'); $sendto = "List@emails.here"; $emailsubject = "Webstats Report For $cdate."; while ($row = mysql_fetch_row($result)) { $to = $row[0]; $from = $row[1]; $subject = $row[2]; $message = $row[3]; $datetime = $row[4]; $eachmessage = "<p> <table width=\"400\"> <tr> <td> <hr width=\"400\"> To: $to<br> From: $from<br> On $datetime<br> <br> $subject<br> <br> $message </td> </tr> </table> </p>"; } $emailmessage = "<html> <body> <p>Here is a list of the messages that have been exchanged in the last 24 hours using the webstat system system.</p> $eachmessage </body> </html>"; // To send HTML mail, the Content-type header must be set $headers = 'MIME-Version: 1.0' .

I am new at php. I am trying to loop a number in each click of a button. See attached picture for reference. 1 should iterate after the click of the button and will stop to iterate when it gets to 5.
Here is my code:
<!DOCTYPE html>
<html>
<body>
<div>Question <?php $num = 5; $n = 1; $n <= $num; echo $n; ?> of <?php echo $num;?></div>
<form method="post"> <button id="button" class="button" value="add" name="add">Click</button> </form>
</body>
</html>
If I try to loop it this way,
<!DOCTYPE html>
<html>
<body>
<div>Question <?php $num = 5; for($i = 1; $i <= $num; $i++){ echo $i; } ?> of <?php echo $num;?></div>
<form method="post"> <button id="button" class="button" value="add" name="add">Click</button> </form>
</body>
</html>
the result is Question 12345 of 5.
Hello, i have the code below and i need to have all results in a variable as a string, inside the loop they are displayed how i want but outside will echo the last result. Thank You. Code: [Select] foreach($_POST as $key=>$value){ if (is_numeric($value)) { $valoare = "$value,"; } } echo $valoare; This topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=321230.0 This is more of a technical question that i could not find the answer to pn the php.net manual pages. take the folowing example code: foreach ($array as $key => $value){ $tempvariable = some_property_of($value); } unset($tempvariable); is that unset statement needed? Does PHP automatically destroy the variables once the foreach loop is left? I have this simple while loop which retrieves data from a mysql query and displays several links on my homepage. I would like to avoid using the php get function and add query strings to my urls I am thinking of using session variables but I need help and I'm pretty sure this can't be done. When a visitor clicks a link from the several ones displayed by the while loop, that particular variable would be set in a session. In my code, the session will always send the last var Can this be done? Code: [Select] <? session_start(); // Start Session Variables $result = mysql_query("my query"); while($slice = mysql_fetch_assoc($result)){ $url = $slice['url']; $name = $slice['name']; ?> <a href="<? echo $url; ?>"><? echo $name; ?></a> <? } $_SESSION['name'] = $name; // Store session data ?> Hello, If I have this string: $tags="baseball glove face" (this can vary from 1 to 15 different words) how would i loop through and divide these into different $tag1=baseball $tag2=glove $tag3=face .. and so on (if more words) Thanks for help First page adds a new job number, then the order page loaded with the job number id as a get id.

I've tried several options and know I'm on the right track, but no go. The customer will choose how many payments and the script below will loop that many times - I have that part working - but the calendar I'm using with the variables above is the issue. Here's the code I'm using. while ($balance > 0){ if ($balance>$monthlypayment){ $myCalendar = new tc_calendar("date" . $paymentnumber, true);$myCalendar->setIcon("images/iconCalendar.gif");$myCalendar->setDate($scheduledate, $schedulemonth, $scheduleyear); //output the calendar $myCalendar->writeScript(); echo " "; echo "<input type=\"text\" name=\"payment" . $monthlypayment . "\" value=\"" . $monthlypayment . "\">\n"; $paymenttotal=($monthlypayment+$paymenttotal); $balance=round(($invoicetotal-$paymenttotal),2); echo " Balance: $balance\n"; $schedulemonth++; if ($schedulemonth==13){ $schedulemonth=1; $scheduleyear=($scheduleyear+1); } echo "<br>\n"; } if ($balance<$monthlypayment||$balance==$monthlypayment){ $myCalendar = new tc_calendar("date" . $paymentnumber, true);$myCalendar->setIcon("images/iconCalendar.gif");$myCalendar->setDate($scheduledate, $schedulemonth, $scheduleyear); //output the calendar $myCalendar->writeScript(); echo " "; echo "<input type=\"text\" name=\"payment" . $paymentnumber . "\" value=\"" . $balance .

So my question is actually 3 fold. 1. How do I increase the variable count in the loop above. 2. How do I put the <input type="hidden".......> in the form so that it loops through and catches the increasing variables 3. How do I loop through on the insertion page after the form is submitted to catch how many inserts to the database are needed. This one has me bent over. Hello, I'm working on a script which should read lines from a file keyword.txt create a new file with that variable name, insert the content close and loop through all the lines in the keyword file. The loop itself works but now that i'm adding the fopen fwrite and fclose i'm running into trouble. I'm not that great a coder and have pieced this together so far. I'd appreciate any suggestions on how to fix the fopen and other file functions to create unique files using the keywords from the file Thanks in advance <?php $read_file = file('keywords.txt'); foreach($read_file as $var) { $file = fopen($var, "x"); $content = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"> <html xmlns=\"http://www.w3.org/1999/xhtml\"> <head> <meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /> <title>This is the title</title> </head> <body> <h2>The keyword is $var</h2> <p><p> </body> </html>"; fwrite($file, $content); fclose($file); } ?> Hello all, I'm new to PHP and new to this forum (although I have benefitted from your help already -cheers!). However, this time I cannot find the answer I need/recognise/understand.. I have a form and want to conduct tests on each field returning an error message as a session variable if the test fails. The test will be different for some of the fields, and the error message is specific to each field. If there is an error in any one of the fields I want to be redirected to a failure page where all of the error messages are displayed, otherwise I am sent on to another page. I have already written and tested a function to sanitise the incoming form data, so that's not a problem - it's just how to loop through and test. I can guess that there are many ways to do this but I need to understand why one option is better than another, and follow the syntax used (it's all part of my steep learning curve) The approach I have thought to use is to create an array holding the field name, the test and the message, then loop through using foreach, applying the array values into the test and creating the error message....but it's not working for me. The other method is to declare a variable $Stop='No' and if the loop identifies an error, part of the output is to change this to 'yes' and through that redirect to the error page. I'd really welcome your advice and tuition....cheers.. my code so far is... Code: [Select] $Stop='No'; $StaffPassCheck=sanitisealphanum($_POST['PasswordCheck']); $Errors[0]['value']= sanitisealphanum($_POST['FirstName']); $Errors[0]['message']='Please re-enter your name'; $Errors[0]['test']=($StaffFname=""); $Errors[1]['value']= sanitisealphanum($_POST['Surname']); $Errors[1]['message']='Please re-enter your surname'; $Errors[1]['test']=($StaffSname=""); $Errors[2]['value']= sanitisealphanum($_POST['Post']); $Errors[2]['message']='You must select an option'; $Errors[2]['test']=($StaffPost="Select Value"); $Errors[3]['value']= sanitisealphanum($_POST['Username']); $Errors[3]['message']='You must select an option'; $Errors[3]['test']=($StaffUser=""); $Errors[4]['value']= sanitisealphanum($_POST['Password']); $Errors[4]['message']='Please re-enter your password'; $Errors[4]['test']=($StaffPass=""); $Errors[5]['value']= sanitisealphanum($_POST['PasswordCheck']); $Errors[5]['message']='Sorry, your passwords do not match'; $Errors[5]['test']=($StaffPass===$StaffPassCheck); foreach ($Errors as $key => $Value){ if ( $Errors['test']=true ){ $Stop='Yes'; return $_SESSION[$key]=$Value['message']; } } if ($Stop='Yes'){ header('Location.test.php'); die(); }else{ header('Location.indexp.php'); } Here is the number: $GrandTotal = "68.835"; $Deposit = round($GrandTotal , 2) * .5; echo $Deposit; I am looking for: 68.84 but the function doesn't seem to work right. Any help? Hi, I have a page on which decimal values are entered. The problem is however that sql does not recognize the comma (the european decimal separator) as the decimal separator. How can I change the input to something that sql can accept? And what if someone enters a number in English format (a dot instead of a comma)? Or uses thousands-separators? Has anyone have experience with this? Greetz, Winelover Hi guys, I've got a line of code that asks for a column called "distance_completed" to be displayed as part of a string. This column tells users how far people have run in a running race. I set up this field in my database to 11,3 so all distances appear with a decimal at the end, and then 3 digits after the decimal place. How would I alter the code so that the numbers that don't have any information in the places section just appear as integers Eg: 42 instead of 42.000 (for someone who ran exaclty 42km) and those that do have information in the decimal places appear correctly (eg: if a person ran 42km and 195m, it would appear as 42.195). I think this is probably the only line of code that would need modification: Code: [Select] echo ($row['time'] != null)?$row["time"]:"dnf at ".$row["distance_completed"]."km."; Hello all it is my 1st post so welcome me i need to make php check if the number is 3 decimals and the last digit is 0. if it is 0 it will echo something if it is not 0 then it will echo something else i came up with this code but i dont know how to make it check if the decimal has a trail of 0 (zero) Code: [Select] <?php if(strpos($Price,".090") !== false){ echo "there is 0 at the end of the price"; //here code to remove the 0 if it is possible }else{ echo "there is no 0 at the end of the price"; // echo the normal price } ?> this will work correctly for the price $4.090 , 12.090 etc but how can i do it in php so it will check if there is 0 at the end of the decimal? Code: [Select] $_POST['amount'] = intval($_POST['amount']); if ($_POST['amount'] < 0){ message($lang_common['Bad request']); } if (!is_numeric($_POST['amount'])){ message($lang_common['Bad request']); } echo $pun_user['gold']; echo '<br>'; echo $_POST['amount']; exit; if I enter 0.05 in my gold input textbox and submit it, it reads 0, it doesn't read the decimal values, i need it to read them, but I also need it to be secure and use intval.. help |
