PHP - $data2 = $data2 + $data; Does Not Work
Hi
Im plotting a graph using JPGraph. The first plotted line uses $data as its source. It works like a charm, I collect the data from a MySql database. However, now I want to plot a new line. I want that line to use the same data but I want to add each value to the value before and so on. This is my code that dosent work. Code: [Select] while ($row = mysql_fetch_array($result)) { $data[] = $row['EF0000000DBBDD1D']*6/1000; $data1[] = strtotime($row['DATETIME']); $data2[] = $data2 + $data; } echo "-----------------------------"; print_r ($data); print_r ($data2); The result Im looking for is this: Code: [Select] $data = 2, 2, 2, 2, 2, 2, 2, 2, 2..... $data2 = 2, 4, 6, 8, 10, 12, 14....... I thought that this should be easy but I just cant seem to find the answer. Any help is appreciated. Similar TutorialsHi all, I am lost again in this PHP world.

The codes are in 4 text files about 30MB each. The codes are 3 per line, then a line break, and 3 more. Ive written a script to parse out the line breaks, turn the data into an array, then loop over thay array and insert into the DB. The problem is these scripts take minutes to run using file_get_contents and by the time the data is ready the mmysql connection is gone. Plus even these files only work after Ive cut the files into about 1MB each, so each file is 30 smaller ones. Is there a way to just put the text file on the server, and have php search it using a GREP like function that won't be such a burden to work with. Any advice helps. James Can anyone point out what's wrong with my feedback.php? It used to work fine and I don't think I did anything but it stopped working - i.e. I had it on a site which I never looked at and when I did look at it I noticed the rubbish written to the database had inexplicably stopped being written there some months ago..... since then I've tried to clean it up and use it elsewhere ( I'm a baby at php and most else) but I can't get it to go right. In this attempt it was giving me the dreaded 'headers already written..' error and I (after googling) took out all the blank space I could and extra comments and what not and stuck in some debugging prints for me and now I get no errors but I get nothing written to the database and no email sent to me.

Here the musings that led to the code: Depending on num dimensions, we could do, foreach($result as $k => $v) {echo $k." ".$v} to view and work with data (adding sub foreach loops accordingly; i.e. if $v is itself an array) see the results: What do you think: Code: [Select] $ch = curl_init("http://www.aktive-buergerschaft.de/buergerstiftungsfinder"); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $buffer = curl_exec($ch); curl_close($ch); $result = explode(",", $buffer); foreach($result as $k => $v) {echo $k."

Hi all, Thanks for reading. I'm hella frustrated at this script I wrote: for some reason, it will not work correctly. Basically, it works. The first 4 names in the table on the database show up when searched. But, anything past these four names in the database will not show up as a result when searched! I'm pulling my hair out here! It's really simple - take a gander: Code: [Select] if (isset($_POST['submit'])) { $search = $_POST['search']; $searchQuery = mysql_query("SELECT * FROM Accounts WHERE FullName='$search'"); if (mysql_num_rows($searchQuery) == 0) { $result = "Your search returned no results. Please try again."; } else { $results = 1; while ($getSearchResults = mysql_fetch_array($searchQuery)) { $fullName = $getSearchResults['FullName']; $result = "Name: ".$fullName.""; } } } ?> ...and the HTML form... Code: [Select] <form action="search.php" method="post"> <p>Search: <input type="text" name="search" size="35" maxlength="100" /></p> <p><input type="submit" value="Search" name="submit" /></p> <?php echo $result; ?> </form> Does anyone have any ideas? This one requires lots of up front information: I have a page, for this example that I will call page.php. It takes get parameters, and for this example I'll call the parameter "step". So I have a URL like this: page.php?step=1 This page has a form with an action of page.php?step=1. The code on the page validates the posting information. If the information is bad, it returns the user to page.php?step=1; if it is good, it takes the user to page.php?step=2 via header( "location:page.php?step=2" ). So redirection is done by relative path, not full URLs. This all works as expected. Now what I've done is set .htaccess to be HTTPS for this page, via this code: # Turn SSL on for payments RewriteCond %{HTTPS} off RewriteCond %{SCRIPT_FILENAME} \/page\.php [NC] RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L] This works (initially). However, once you try to post the form, it just redirects back to the step=1 version of the page. I really don't know how or why that would be. I'm not sure how else I can explain this or what other information you may have. But it's frustrating to not get a page working in HTTPS that works in HTTP. Very odd. Any suggestions? (I don't even really know the best location to figure out when/why it's redirecting back to the original page.) Hi.., I use below method to export data to excel. header('Content-type: application/ms-excel'); header('Content-Disposition: attachment; filename=abc.xls'); if I run the script from the server. (http://localhost/export.php) it is work. (pop-up window if i want save or open the file) but if i run the script from the client (http://192.168.1.5/export.php) it is not work. (nothing happen) any idea how to solve this? require_once 'includes/upload.class.php'; $upload = new uploads(); $details = $upload->getFileInformation($id); <?php echo $details['upload_desc']; ?> then here the class. require_once 'db.class.php'; class uploads extends database { private $uploadData; function uploadFile() { public function getFileInformation($id) { $this->uploadData = $this->readData("uploadfiles", "upload_id", $id); return $this->uploadData; } But it wont work! Some of you may have seen one of my many posts about email issues. Some users don't get them, and I have determined it is probably because we are marked as spam.
We are a service that grades sales team members on their phone skills. Listening to pre-recorded calls, grading and uploading them to our site, and then another part of our business looks them over and sometimes leaves a message that then get's forwarded to this persons work email.
I have determined there is ways to get marked as spam as default by not having an opt out link. This is not an option, these sales members employer has opted in, and the emails are going to work related accounts hosted at that employer. Also, if one of these staff members is not so bright, or disgruntled they may mark us as spam anyways. The bottom line is that we have very little control over whether we are or are not marked as spam.
So we want to start looking into sending text messages and this is where I start to question how good of an idea this is.
First off, if it was me, and the messages where being sent to a device that my employer did not provide, I would in no way want work related text messages coming to me. Unless there is a vested interest in getting them. IE, I'm the boss at this place and am always on the clock. What if you are on the bottom? It's just a job for you.
What if it is a pre-paid device, text messages cost money. What then? What if they don't even have, or want a cell phone?
The short of it is this. If I'm at a job that is just another job, and this employer tells me that I have to get these messages. I'm going to look for another job. I see the organizations having continuous issues and complaints from their employees. Thus us as a business having issues keeping clients.
What am I getting into here? What are your opinions on this matter? What are your recommendations as to alerting users of something on our site that we can rest assured are being received 100% of the time?
Thanks!

Am new here - looks like a great foru! I would sincerely appreciate any help anyone can give me. I have been trying to solve my problem for hours and I am not having any luck, so I thought I would post and see if anyone can help. I am very stuck and am not making much progress on this project, and I am certain the answer is very simple. I am constructing a form to collect data for a specialized purpose. The form and program actually work for its intended function, but I am trying to enhance the user experience by preventing customers from having to reenter all of their data should there be a problem with any of the data submitted. I have been able to do that with the contact form portion, but what I am having trouble with is the portion which has as many as 400 possible entries. So, in a nutshell, if the customers contact data is incomplete or in error, the form will ask them to return to the page and correct things. The previous data entered has been saved in the session and the input value will equal the previous entry. i.e. <tr> <td align="right" class="infoBox"><?php echo ENTRY_EMAIL_ADDRESS; ?></td> <td align=left><?php echo "<input type=text name='cemail' value=\"$cemail\" size=35 maxlength=35>" ?></td> </tr> Works perfectly, all well and good there. On the other 400 more or less entries, I am having a difficult time tweaking the string concatenation to work to achieve similar results. There are 4 columns each with $points entries asking for a dimension in either feet or inches. The <input name=> is one of ptaf,ptai,ptbf,ptbi, appended programatically with the corresponding row number or data point. i.e. "ptaf1", "ptai1", etc... This is produced by the example below and works perfectly also. <?php { $points=100; $i=1; while ($i <= $points) {echo ' <tr><td align="center" width="6"><b> ' .$i . '</b></td> <td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" name="ptaf'.$i.'" size=4 maxlength=3> </td> <td align="right" NOWRAP>A' .$i . ' (in) <input type="text" name="ptai'.$i.'" size=4 maxlength=4> </td> <td align="right" NOWRAP>B' .$i . ' (ft) <input type="text" name="ptbf'.$i.'" size=4 maxlength=3> </td> <td align="right" NOWRAP>B' .$i . ' (in) <input type="text" name="ptbi'.$i.'" size=4 maxlength=4> </td> '; $i++; } } ?> I am trying to add <input value=$ptai.$i> for each field but as I mentioned I am not having any luck. It seems as if I have tried every combination imagineable, but still no luck. My head is spinning! The closest I seem to have gotten was with this: <td align="right" NOWRAP>A' .$i . ' (ft) <input type="text" size=6 maxlength=3 name="ptaf'.$i.'" value="' . "$ptaf" . $i . '" ></td> But line 17 for example returns this: <input type="text" value="17" name="ptaf17" maxlength="3" size="6"> To recap, I am trying to have the value set to whatever the customer may have entered previously. Again, I would most appreciate any help anyone can give me. If you need clarification on anything please let me know. Thanks AJ Hello to all, I have problem figuring out how to properly display data fetched from MySQL database in a HTML table. In the below example I am using two while loops, where the second one is nested inside first one, that check two different expressions fetching data from tables found in a MySQL database. The second expression compares the two tables IDs and after their match it displays the email of the account holder in each column in the HTML table. The main problem is that the 'email' row is displayed properly while its while expression is not nested and alone(meaning the other data is omitted or commented out), but either nested or neighbored to the first while loop, it is displayed horizontally and the other data ('validity', 'valid_from', 'valid_to') is not displayed.'
Can someone help me on this, I guess the problem lies in the while loop? <thead> <tr> <th data-column-id="id" data-type="numeric">ID</th> <th data-column-id="email">Subscriber's Email</th> <th data-column-id="validity">Validity</th> <th data-column-id="valid_from">Valid From</th> <th data-column-id="valid_to">Valid To</th> </tr> </thead> Here is part of the PHP code:
<?php
while($row = $stmt->fetch(PDO::FETCH_ASSOC))
{
echo '
<tr>
<td>'.$row["id"].'</td>
';
while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
echo '
<td>'.$row1["email"].'</td>
';
}
if($row["validity"] == 1) {
echo '<td>'.$row["validity"].' month</td>';
}else{
echo '<td>'.$row["validity"].' months</td>';
}
echo ' <td>'.$row["valid_from"].'</td>
<td>'.$row["valid_to"].'</td>
</tr>';
}
?>
Thank you. I have two tables. Table Name:Users Fields: User_name user_email user_level pwd 2.Reference Fields: refid username origin destination user_name in the users table and the username field in reference fields are common fields. There is user order form.whenever an user places an order, refid field in reference table will be updated.So the user will be provided with an refid Steps: 1.User needs to log in with a valid user id and pwd 2.Once logged in, there will be search, where the user will input the refid which has been provided to him during the time of order placement. 3.Now User is able to view all the details for any refid 3.Up to this we have completed. Query: Now we need to retrieve the details based on the user logged in. For eg: user 'USER A' has been provided with the referenceid '1234' during the time of order placement user 'USER B' has been provided with the referenceid '2468' during the time of order placement When the userA login and enter the refid as '2468' he should not get any details.He should get details only for the reference ids which is assigned to him. <?php session_start(); if (!$_SESSION["user_name"]) { // User not logged in, redirect to login page Header("Location: login.php"); } $con = mysql_connect('localhost','root',''); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("login", $con); $user_name = $_POST['user_name']; $refid = $_POST['refid']; $query = "SELECT * from reference,users WHERE reference.username=users.user_name AND reference.refid='$refid' AND "; $result = mysql_query($query) or trigger_error('MySQL encountered a problem<br />Error: ' . mysql_error() . '<br />Query: ' . $query); while($row = mysql_fetch_array($result)) { echo $row['refid']; echo $row['origin']; echo $row['dest']; echo $row['date']; echo $row['exdate']; echo $row['username']; } echo "<p><a href=\"logout.php\">Click here to logout!</a></p>"; ?> <html> <form method="post" action="final.php"> Ref Id:<input type="text" name="refid"> <input type="submit" value="submit" name="submit"> </html> Hi, after banging my head against the wall for a while thinking this would be a simple task, I'm discovering that this is more complicated than I thought. Basically what I have is a link table linking together source_id and subject_id. For each subject there are multiple sources associated with each. I had created a basic listing of sources by subject... no problem. I now need a way of having a form to create an ordered list in a user-specified way. In other words, I can currently order by id or alphabetically (subject name lives on a different table), but I need the option of choosing the order in which they display. I added another row to this table called order_by. No problem again, and I can manage all of this in the database, however I want to create a basic form where I can view sources by subject and then enter a number that I can use for sorting. I started off looping through each of the entries and the database (with a where), and creating a foreach like so (with the subject_id being grabbed via GET from the URL on a previous script) Code: [Select] while($row = mysqli_fetch_array($rs)) { //update row order if (isset($_POST['submit'])) { //get variables, and assign order $subject_id = $_GET['subject_id']; $order_by = $_POST['order_by']; $source_id = $row['source_id']; //echo 'Order by entered as ' . $order_by . '<br />'; foreach ($_POST['order_by'] as $order_by) { $qorder = "UPDATE source_subject set order_by = '$order_by' WHERE source_id = '$source_id' AND subject_id = '$subject_id'"; mysqli_query($dbc, $qorder) or die ('could not insert order'); // echo $subject_id . ', ' . $order_by . ', ' . $source_id; // echo '<br />'; } } else { $subject_id = $_GET['subject_id']; $order_by = $row['order_by']; $source_id = $row['source_id']; } And have the line in the form like so: Code: [Select] echo '<input type="text" id="order_by" name="order_by[]" size="1" value="'. $order_by .'"/> (yes I know I didn't escape the input field... it's all stored in an htaccess protected directory; I will clean it up later once I get it to work) This, of course, results in every source_id getting the same "order_by" no matter what I put into each field. I'm thinking that I need to do some sort of foreach where I go through foreach source_id and have it update the "order_by" field for each one, but I must admit I'm not sure how to go about this (the flaws of being self-taught I suppose; I don't have anyone to go to on this). I'm hoping someone here can help? Thanks a ton in advance This could be PHP or MySql so putting it in PHP forum for now... I have code below (last code listed) which processes a dynamically created Form which could have anywhere from 0 to 6 fields. So I clean all fields whether they were posted or not and then I update the mySQL table. The problem with this code below is that if, say, $cextra was not posted (i.e. it wasnt on the dynamically created form), then this code would enter a blank into the table for $cextra (i.e. if there was already a value in the table for $cextra, it gets overwritten, which is bad). What is the best way to handle this? I'm thinking i have to break my SQL query into a bunch of if/else statements like this... Code: [Select] $sql = "UPDATE cluesanswers SET "; if (isset($_POST['ctext'])){ echo "ctext='$ctext',"; } else { //do nothing } and so on 5 more times.... That seems horribly hackish/inefficient. Is there a better way? Code: [Select] if (isset($_POST['hidden']) && $_POST['hidden'] == "edit") { $cimage=trim(mysql_prep($_POST['cimage'])); $ctext=trim(mysql_prep($_POST['ctext'])); $cextra=trim(mysql_prep($_POST['cextra'])); $atext=trim(mysql_prep($_POST['atext'])); $aextra=trim(mysql_prep($_POST['aextra'])); $aimage=trim(mysql_prep($_POST['aimage'])); //update the answer edits $sql = "UPDATE cluesanswers SET ctext='$ctext', cextra='$cextra', cimage='$cimage', atext='$atext', aextra='$aextra', aimage='$aimage'"; $result = mysql_query($sql, $connection); if (!$result) { die("Database query failed: " . mysql_error()); } else { } Here's the code that deals with the client side:
<?php
session_start();
if(!isset($_SESSION['Logged_in'])){
header("Location: /page.php?page=login");
}
?>
<!DOCTYPE Html>
<html>
<head>
<!--Connections made and head included-->
<?php require_once("../INC/head.php"); ?>
<?php require_once("../Scripts/DB/connect.php"); ?>
<!--Asynchronously Return User Names-->
<script>
$(document).ready(function(){
function search(){
var textboxvalue = $('input[name=search]').val();
$.ajax(
{
type: "GET",
url: 'search.php',
data: {Search: textboxvalue},
success: function(result)
{
$("#results").html(result);
}
});
};
</script>
</head>
<body>
<div id="header-wrapper">
<?php include_once("../INC/nav2.php"); ?>
</div>
<div id="content">
<h1 style="color: red; text-align: center;">Member Directory</h1>
<form onsubmit="search()">
<label for="search">Search for User:</label>
<input type="text" size="70px" id="search" name="search">
</form>
<a href="index.php?do=">Show All Users</a>|<a href="index.php?do=ONLINE">Show All Online Users</a>
<div id="results">
<!--Results will be returned HERE!-->
</div>
search.php
<?php //testing if data is sent ok echo "<h1>Hello</h1><br>" . $_GET['search']; ?>This is the link I get after sending foo. http://www.family-li...php?&search=foo Is that mean it was sent, but I'm not processing it correctly? I'm new to the whole AJAX thing. Say there is a complex opt in process where people start to enter their data but certain questions stop them where they close out of the page. They already entered their data and I feel there is a way to grab it and post it to mysql even though they do not click submit.
How would this be done?
A super simple example (proof of concept) or a link to a tutorial would be very useful.
Edited by brentman, 23 September 2014 - 10:42 AM. Hi I am trying to select and order data/numbers from a colum in a mysql data base however i run the code and it returns no value just a blank page no errors or any thing so i think the code is working right but then it returns no result? Please help thanks Here is the code: <?php $host= "XXXXXX"; $mysql_user = "XXXXXX"; $mysql_password = "XXXXXX"; $mysql_database = "XXXXXXX"; $connection = mysql_connect("$host","$mysql_user","$mysql_password") or die ("Unable to connect to MySQL server."); mysql_select_db($mysql_database) or die ("Unable to select requested database."); $row = mysql_fetch_assoc( mysql_query( "SELECT XP FROM Game ORDER BY number DESC LIMIT 1" ) ); $number = mysql_result(mysql_query("SELECT XP FROM Game ORDER BY number DESC LIMIT 1"), 0); echo "The the highest XP is $number"; ?> I'm pulling data from an xml file and I'm getting a lot of duplicates. How can I remove the duplicates from the query? Code: [Select] foreach($xml->category->subcategory as $category){ echo $category[id]; }//end foreach |
