PHP - Need Help Averaging Array Integers Within If Else Block
I almost have this right, but not quite. I am trying to echo out the average score if a person scored above 70 and my averaging isn't correct. It should echo out 89, but instead the number is 63.25. The averaging is the only part not working. Everything else works as intended. I might not have my curly braces in the proper order or something. I think it's something stupid I am forgetting. Here is my code.

Code: [Select] if( date('j') < 1 && > 14) { $EnrollDate = "1/".date('n')."/".date('y'); }else { $EnrollDate = "15/".date('n')."/".date('y'); } What could be wrong here, i cant work! i hit a wtf moments print $_POST['idName']; // prints 0, correct, the value of the selected select element item is indeed 0 print '<br>'; $value = intval($_POST['idName']); // otherwise its a string if($value == 'empty') { print '<br>wtf does this get printed?'; } the $values value is the number zero, not the string 'empty', so why does it eval as one? I am wondering how can I insert integers in the database without manually input it in the form. I am looking to fill the product_id and customer_id table. I would do it but only by sequence and '' quotes at the VALUE part of an INSERT statement. Also condition the insert of product_id and customer_id according to the id in the SESSION variable. Code: [Select] <?php session_start(); if (isset($_SESSION['id'])) { $userid = $_SESSION['id']; $username = $_SESSION['username']; $fname = $_POST['firstname']; $lname = $_POST['lastname']; $telephone = $_POST['telephone']; $city = $_POST['city']; $state = $_POST['state']; $itemname = $_POST['product_name']; $price = $_POST['price']; $details = $_POST['details']; $category = $_POST['category']; $subcategory = $_POST['subcategory']; $product_id = $_POST['product_id']; $customer_id = $_POST['customer_id']; $date_sold = $_POST['date_sold']; $sqlinsert = "INSERT INTO customers (id,firstname,lastname,telephone,city,state,product_name,price,details) VALUES('','$fname','$lname', '$telephone','$city','$state','$itemname','$price','$details')"; $sqlinsert2 = "INSERT INTO products (id,product_name,price,details,category,subcategory) VALUES('','$itemname','$price','$details','$category','$subcategory')"; $sqlinsert3 = "INSERT INTO sales (id,product_id, customer_id, date_sold) VALUES('','$product_id','$customer_id','$date_sold')"; $enterquery = mysql_query($sqlinsert) or die(mysql_error()); $enterquery2 = mysql_query($sqlinsert2) or die(mysql_error()); $enterquery3 = mysql_query($sqlinsert3) or die(mysql_error()); } ?> The above insert its respective fields in each table but how is it possible to INSERT it according to the SESSION['id]; so that it INSERT according to the costumer id plus that it generates and INSERT automatically in the product_id and customer_id related to the product_id and customer_id fields in products and customer table? without manually doing it. any references will be appriciated because the above code seems like the product_id and customer_id won't INSERT in relations to the customer and product table. One more thing the product_id and customer_id won't be pass from the form to this file but rather a value will be INSERT it in their field according to the id in customer and products table. Hi everybody, a few dasy ago i found a function which translates integers into text like this:
echo $number->written_number(101); // one hundred one
but i've got a problem, this function works fine on russian language, but that this function translate in 3 languages:
russian, english and ukrainian like this:
echo $number->written_number(101); // сто один - one hundred one - сто один
how can i add english and ukrainian languages?
When i tried to add this manually, it was okay but in one moment i received error, and all my script is broked, and now i don't know what to do, i've got a few hours to complete this test work, but unfortunately i've got no idea how to do this(
Pls help me somebody, i will infinitely grateful!!!

as you can see i tried to glue array with russian language words with array with english laguage words.
Probably i've got somethink like this:
$number = new numberTransfer();echo $number->written_number(101); сто один one one hundredодин one damn bullshit... Please people help me:) Is it possible to perform type declaration which allows either an integer or a string digit (i.e. ctype-digit) instead of the following?
function someFunction(int $id){}
Looking at functions.arguments.type-declaration, I expect not. If not, would you recommend type casting before calling the function or removing type declaration from the function and performing the check manually within the function and throwing an applicable exception? Thanks Hi,
Is there any way to use the inbuilt filter functions in PHP to filter for integer values greater than 256? All examples that I saw had a max_range of 256. Kindly suggest. Thanks.
Well the topic may not sound very explicit. So I'll do my best to explain it here. I have a pull down menu as part of a form, which contains the months of the year. I'm trying to store the value of this form entry using the $_POST['month'] variable into a database but first, I need to convert the month values into their corresponding integer values( that is 1 for January, 2 for February etc), in order to easily do date calculations later down the road. Any ideas about how to do this? It may be helpful to include the code for the pull down menu. Code: [Select] <p><tab> Date of Birth: <?php //Make the month pull down menu. //Array to store months. $months = array (1 => 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'); print '<select name= "month">'; foreach ($months as $key => $value) { print "\n<option value=\"$key\">$value</option>"; } print '</select>'; ?> </tab> <tab> <?php //Make the day pull down menu print '<select name= "day">'; for ($day = 1; $day <= 31; $day++) { print "\n<option value=\"$day\">$day</option>"; } print '</select>'; ?> </tab> <tab><?php //Make the year pull down menu print '<select name= "year">'; $start_year = date('Y'); for ($y = ($start_year - 18); $y >= 1900; $y--) { print "\n<option value=\"$y\">$y</option>"; } print '</select>'; ?> </tab> </p> Hi, I'm trying to retrieve the integer value between the <span> tag from a HTML source code.
HTML source code:
<span> (3861822) </span>This is the php code:
<!DOCTYPE html>
<html>
<body>
<?php
//use curl to get html content
function getHTML($url,$timeout)
{
$ch = curl_init($url); // initialize curl with given url
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]); // set useragent
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // write the response to a variable
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects if any
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); // max. seconds to execute
curl_setopt($ch, CURLOPT_FAILONERROR, 1); // stop when it encounters an error
return @curl_exec($ch);
}
$html=getHTML("http://www.alibaba.com/Products",10);
preg_match("/<span>(.*)<\/span>/i", $html, $match);
$title = $match[1];
echo $title;
?>
</body>
</html>
Whenever I try to run it, this error will come out: Notice: Undefined offset: 1 in C:\xampp\htdocs\myPHP\index.php on line 19.
How to correct it so that it will display all the integer value within the tag name but without the bracket? Thanks
Edited by Raex, 20 August 2014 - 01:38 AM. Hello, I'm having a bit of a problem here, all help to this issues would be much appreciated I am trying to use text boxes to insert numbers into the database based on what is inputed. If I have a string, like this for example: $variable = 09385493; And I want to insert it into the database like this: mysql_query("INSERT INTO integers(number) VALUES ('$variable')"); When checking the integers table in my database, looking at the number field, the $variable that was inserted is outputted as 9385493 Notice the number zero was taken out of the front of the number. If the number is double 0's (009385493), both of those zero's would disappear, too. Thanks I have been reading most spambots use UTC-12 timezone and PHbb has a hack to block UTC-12, but I dont have the file I am looking to get the UTC ( or GMT ) time from the referring page any ideas? I draw contents from a database. Some of the texts contain a footnote, which is formatted using a div class. Following the HTML of this:
<div class=""footnotes"">
<br>
<hr align=""left"" noshade=""noshade"" size=""1"" width=""150"" />
<blockquote> <a href=""#f1"" name=""fn1""> <span class=""superscript""> * </span>
</a>Some footnotetext</blockquote></div>
Since my bibliography uses data from the database as well, the footnote now appears before the references, but I would like it at the very bottom of the page. I was thinking of using preg_replace in order to separate the textfield into two variables, one for the text itself, the other one for the footnote (it is always just one) and integrate after the bibliography is compiled.
Unfortunately, it seems that the preg_replace does not work. It always displays the whole content of the textfield. Here's the PHP:
$text = preg_replace('/(.*)(\div class=\"footnotes\"\>.*?\<\/div\>)/s', '$1', $result['text']);$footnote = preg_replace('/(.*)(\div class=\"footnotes\"\>.+?\<\/div\>)/s', '$2', $result['text']);
echo '<div align="justify"><span style="font-family:Georgia;font-size:16px;">' . $text;
***BIBLIOGRAPHY***
...
echo $footnote;
Maybe someone has an idea how to deal with that. I tried it on phpliveregex. There search string works fine. Many thanks for any help.
How is it that a site can forward to my site without a trace? www.2mysite.com is forwarding traffic to www.mysite.com but $page_name = $_SERVER['HTTP_REFERER']; echo $page_name; does not show www.2mysite.com as the referring site...how does one hide this? Help? how to block someone from visiting my page using ip adress ? this is the case if someone come to my site then we record the ip address and put it into database. when the visitor come again with the same IP they cannot see my page (block them) and redirect it to somewhere page. It's one of those days after a long weekend and a rainy morning. Simply trying to get the correct message depending on the variable's value
if($a = 'one'){
echo "POOR";}
if($a = 'two'){
echo "GOOD";}
if($a = 'three'){
echo "VERY GOOD";}
if($a = 'four'){
echo "EXCELLENT";}
Not sure if I need to use ==, extra quotes, or ELSEIF for the best result.
Hey
Need help i am having a mental block
when I fill in the form and click send it sends the form but looks like this
Name: , Email: , Subject: , Message:the form data is <?php $name = $_POST['name']; $email = $_POST['email']; $subject = $_POST['subject']; $message = $_POST['message']; $formContent = "From: $name, \n Email: $email, \n Subject: $subject, \n Message: $message"; $recipient = "email@email.com"; $subject = "Website Request"; $mailheader = "Website \r\n"; mail($recipient, $subject, $formContent, $mailheader); echo "Your message was sent" . " - " . "<a href='index.html' style='text-decoration: none; color: #d03837;'>Return Home</a>"; ?>Anyone with any ideas I'm trying to clean up some past coding for a project of mine and this block keeps standing out like a sore thumb, but it works and i can understand it. What it's doing is comparing each of the users submitted data to the admin-set data and then flagging if there any errors or not. Any suggestions on a different approach? Code: [Select] foreach ($_SESSION['usersData'] as $k => $v) { foreach ($this->info as $m => $n) { if ($m == $k) { if ( ($n['required'] && ( empty($v) || !isset($v) ) ) ) { $_SESSION['errors'][$k] = TRUE; } elseif ( (!$this->escape_data($v,$n['type'])) && ($n['required']) ){ $_SESSION['errors'][$k] = true; } elseif ($n['required'] && ($v == $n['default'])) { if ($n['readonly'] != true) $_SESSION['errors'][$k] = true; } elseif ($n['required'] && $n['readonly'] && ($v != $n['default']) ) { # Box is required, set to readonly and has a default value, if this triggers then the user has tampered with our form. $_SESSION['usersData'][$k] = $n['default']; } elseif (isset($_SESSION['errors'][$k])) { unset($_SESSION['errors'][$k]);# = false; } } elseif ( isset($this->info['file']) ) { if ($this->info['file']['required'] && $_FILES['file']['size'] == 0) { $_SESSION['errors']['file'] = TRUE; } else { unset($_SESSION['errors']['file']); } } } } So I'm debating whats the best method. I'm aware that catch/blocks should be used in exceptional cases but what if it saves me from having 4 nested if/else conditions? The following is code for an xbox registration site Code: [Select] try { // check code is valid $c1 = $this->input->post('code1',true); $c2 = $this->input->post('code2',true); $c3 = $this->input->post('code3',true); $gt = $this->input->post('gamertag',true); $pass = $this->input->post('password',true); if( $c1 == '' || $c2 == '' || $c3 == '') { throw new FormError("Authorization code invalid."); } // check db for code validation $q = $this->db->query("select * from `codes` where `activated` = 0 and `code` = ".$c1.$c2.$c3." limit 0,1"); if($q->num_rows() != 1) { throw new FormError("Authorization code invalid."); } $r = $q->row_array(); $email = $r["recipient_email"]; $codeGt = $r["gamertag"]; // check valid gamertag $q = $this->db->query("select * from `users` where `gamertag` = '".$gt."'"); if($q->num_rows() > 0) { throw new FormError("Gamertag already exists."); } // validate gamertag /w inputted gamertag if(strtolower($codeGt) != strtolower($gt)) { throw new FormError("Gamertag Invalid"); } $this->_createAccount($email,$pass,$gt); // show register-thanks screen $this->load->view("register-thanks",$data); $success = true; } catch (Exception $e) { $data['error'] = $e->getMessage(); } Hi the I have a PDF form that generates an XFDF file (form field valies in XML form) and I am passing it to PHP for processing. I am having trouble pulling a specific value from the XML block because of the way that the XML data is generated and organized. Please see a sample of the XML block below: 'test.xml' file: Code: [Select] <?xml version="1.0" encoding="UTF-8"?> <xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve"> <annots/><fields> <field name="Non"> <value>Off</value> </field> <field name="PayRequest"> <value>XYZ</value> </field> From the above XML snip it, once it's sent to PHP, I would like to somehow reference the "PayRequest" field value and retrieve the value "XYZ" and assign it to a variable. I have been kicking around some code that I thought should work, but doesn't appear to. If anyone could offer any insight to get it working that would be greatly appreciated. PHP Code: Code: [Select] $prq_ret = simplexml_load_file('test.xml'); foreach($prq_ret->xpath("//field[@name='PayRequest']") as $item) { $row = simplexml_load_string($item->asXML()); //print $item->value; print $row; } |
