PHP - Why Am I Being Asked To Define A Descriptor?
I'm being told I have an undefined variable. Similar to sumUsagekWH (in the code below) there are other placeholders called sumUsageKHW, sumUsageWKWp, sumUsageWKWi and so on. Each script of code looks similar to below where the 'totalUsage' is added into sumUsageKHW, sumUsageKHE and so on. All references are highlighted red below to make it easier to follow.
So, if I am only using these sumUsagesXXXX's as placeholders for the following post....
<input name="electric_charge_total" type="hidden" id="electric_charge_total" value="<?php echo number_format($basic_charge + ($sumUsageKWH * $energy_charge) + ($sumUsageWKWp * $peak_rate) + ($sumUsageWKWi * $intermediate_rate) + ( ($sumUsageWKW+$sumUsageWEW) * $base_rate),"2"); ?>" align="right"/>
how to I define them in PHP?
Based on the code below, they are only used as a way to introduce totalUsage ( it looks silly the way it was done, but later the code will be expanded so it makes sense). What I mean is that totalUsage is being entered (in the below case) into sumUsageKWH from the $sumUsageKWH += $row[totalUsage]

Similar TutorialsI recently migrated from Windows XP to Windows 7, and a PHP package I depend on (mPDF, see http://www.mpdf1.com/mpdf) stopped working. When I call one of its necessary functions, it hangs. I investigated further and found that the crash was happening in a call to file_get_contents, given one parameter, a URL that points to a CSS file. I found that the file_get_contents and file functions both crash when given a URL. Both work normally when given a pathname on the local file system. As I understand it, these functions are supposed to accept a URL if the INI directive allow_url_fopen is enabled. I checked by calling ini_get; it is. In any case, the php.net description of fopen says that if that directive is disabled, "PHP will emit a warning and the fopen call will fail" -- not just hang! It appears as if there is a glaring bug in one of PHP's core functions. I'm very skeptical that that is really the problem, but I don't know what else to suspect. Any ideas? My configuration is Windows 7 Professional with SP1; Apache 2.2.17; PHP 5.2.17. For reference, here is the script I used to investigate this problem. I stepped through it with a debugger, so I didn't bother displaying results. As shown, the script works. When I comment out the second assignment to $path it should produce identical results; instead it hangs. Code: [Select] <?php $isopen = ini_get('allow_url_fopen'); $path = "http://localhost/pdf/cert.css"; $path = "D:/htdocs/pdf/cert.css"; $contents = file($path); $contents = @file($path); $contents = file_get_contents($path); $contents = @file_get_contents($path); ?> In many cases, variable have to be explicitly defined for whatever reason. However, often it is not required for a simple web page script. Yet, even in those cases, if a variable is NOT explicitly defined, the web server error log (example: my_domain.com-error_log) will rack up a lot of entries such as this: Quote [Fri Dec 31 01:31:43 2010] [error] [client 123.123.123.123] PHP Notice: Undefined variable: some_variable_name in /home/my_domain/public_html/some_page.php on line 6 A busy site could result in large error logs... What is considered "best practice"? Should all variables always be explicitly defined with the var key word? Hi all, I was reading a bit in the manual about the defined function. Since i have seen it being used quite a lot to disallow direct access. But one of the comments made me think if there are any alternatives to get the same. it's this comment: http://www.php.net/manual/en/function.defined.php#89886 If i read it correct it tells that defined() seems to be pretty slow. I was thinking, if that is the case what are the alternatives... Does anyone know how to interpret this comment and if there are alternatives? I am not yet a guru tofully understand the results. cheers! err, dunno if i managed to put it in the right thread but if i didn't, please tell me. thank you.
getting back on topic, my father asked me to create a website for a school. i know how to make a website but the problem is, how do i start? should i ask about their objectives or something? color of the webpage etc? in short, i don't know the practicalities and processes used in making a website for a certain client. you could say this would be my first time in doing this (kind of like an on-the-job training) so...any ideas? i would very much appreciate any help given.
I have 3 php's home.php createStep1.php createCheckPass.php createStep2.php home.php unsets some $_SESSION variables if they still exist from previous pages: Code: [Select] if(!empty($_SESSION['ame'])) { unset($_SESSION['ame']); } if(!empty($_SESSION['ject'])) { unset($_SESSION['ject']); } if(!empty($_SESSION['ports'])) { unset($_SESSION['ports']); } if(!empty($_SESSION['session_age_range'])) { unset($_SESSION['range']); } createCheckPass.php gets some posted information from createStep1.php, checks everything is ok and if so sets the above session variables createStep2.php gets the session data set by createCheckPass.php and then gets to work with the user inputting data into the db. The odd problem If createCheckPass.php finds any problems with the posted data it redirects the user back to createStep1.php with the sessions set, createStep1.php then displays the errors with the info set in the sessions to the user and everything works ok. If however the user sends the form from createStep1.php with no problems and the createCheckPass.php passes the user onto createStep2.php, something strange happens... The sessions set by the createCheckPass.php are only ever unset at the home.php, yet somehow createStep2.php loses the sessions and therefore doesn't run. What is even stranger is if i comment out the unsetting of the sessions from the home.php, everything works fine and none of the sessions are lost. Really really odd Summary: createStep2.php is reading the unset session lines of code from home.php when never asked to. Has anyone ever come across anything like this before? I have at the very top of my web page the following. Not inside any function in case that would have a scope issue. Define ('GROUP', '1'); Define ('ROUNDOF16', '2'); Define ('QUARTERFINAL', '3'); Define ('SEMIFINAL', '4'); Define ('FINAL', '5'); Lower down I have if($Round == 5) This works but this if($Round == FINAL) has error Parse error: syntax error, unexpected T_FINAL in ....... I thought this was correct ! im doing it wrong can some one help me ? , thanks { Code: [Select] define('userlevel'( 9="admin" , 1="guest"));} Hi, I have the define(); function where i need to put the variable for directory name which is relative ... How to do that ... Code: [Select] <?php if (TARGET_PLATFORM == FILE_SYSTEM_PLATFORM) { /** * if FILE_SYSTEM_PLATFORM is selected as TARGET_PLATFORM, * then assign root folder adress to FILE_ROOT macro */ define("FILE_ROOT", "$diro"); } public function __construct($fileRoot) { if (is_dir($fileRoot)) { $this->fileRoot = $fileRoot; //if ($this->fileRoot[strlen($this->fileRoot) - 1] != '/' ) { // $this->fileRoot .= '/'; //} } else { die($fileRoot .' is not a directory '); } } ?> When i go with this, it says this: " 'dir name ' is not a directory". But I need the variable for this to work as I want to. Does anyone have an idea? To make it clear, this is only the small part of code, which is a part of the directory root for the directory tree. Imagine a site programmed using full OOP. Where would you store information like this: $companyName = "ABC Ltd"; $companyPhone = "02476 999 999"; $companyAddress etc... Would you just define them in the public scope? (and use global or pass them in when needed??) Is there a better way? They will be needed in more places than just a navigation bar and would be needed by more than one class. i tried googling but didnt really know how to "google it" as i cant think of a short phrase that best describes it.. but i want to chance the database setting of "localhost" in my php script to another websites database how do i acheive this? im having a problem getting this code to work...i know it may not make sence why i would do this but it is for a larger script...is there any reason why it wont echo please? define ('TEST_VAR', 'hello'); $var = "TEST"; echo {$var}_VAR; Ive got a simple function that's counting percentages of the results, and what I want is when the first line does $variable / 100 - to go on 2 decimals(ex. 0.72142141 what I want is to write 0.72). Code: [Select] function postotak(){ $p = $bodovi / 100; $postotak = $p * 100; <HTML> <?php $arr = array("sue" => "betsy", "frank" => "marge"); ?> </HTML> This produces the following HTML page: "betsy", "frank" => "marge"); Its like when I use the => to make my associative array, the code thinks I'm closing the php codeblock and then just prints the rest of it to the screen... My goal was to create a constant that could be included on the pages, that no matter where it was located in the structure, would be able to find the template files, css, images, etc. using the following code: Code: [Select] if($_SERVER['HTTP_HOST'] == "localhost"){ define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']); define('SITEPATH', $_SERVER['DOCUMENT_ROOT']); define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/'); define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/'); } else{ define('SITEURL', 'http://' . $_SERVER['HTTP_HOST']); define('SITEPATH', $_SERVER['DOCUMENT_ROOT']); define('TEMPLATE', $_SERVER['DOCUMENT_ROOT'] . '/incs/template/'); define('CSS', $_SERVER['DOCUMENT_ROOT'] . '/css/'); define('IMAGES', $_SERVER['DOCUMENT_ROOT'] . '/images/'); } I put the above in a variables.php file that is in the includes folder (named incs) and I call it using the typical include statement. The problem is that when I use the constant to grab the CSS file, its not working when using: Code: [Select] <link rel="stylesheet" href="<?php echo CSS . "template.css" ?>" type="text/css" media="screen" /> I can view the page source and it has the path right, but I cannot figure out how to get it to actually pull in the css file. I know the echo command is not correct, at least I dont think it is, but have not been able to figure out any other way. Also, is there a better way to define the constants to the file locations and have it automatically detect whether its on the test server or production and then be able to reference those locations no matter where it is in the structure? Hi , how I can save something into form? I mean , insert something in variable and than insert it into value in the form so when i send the form the value will be send too. I also want that it will be can not change. for example : <input name="email" value="a@s.d"/> but this example can be change if you insert something else. thanks , Mor. <?php if (isset($_SESSION['first_name'])) { echo "<div id=\"login_status\">Welcome, Daniel | <a href=\"BASE_URL sm-login/panel\">My Account</a> | <a href=\"BASE_URL sm-login/logout\">Logout</a></div><!-- Show If Logged In -->"; } ?> this is my code but BASE_URL is a define variable containing = http://localhost/ when i run the script php treats it as just BASE_URL e.g. BASE_URL%20sm-login/pane.php not http://localhost/sm-login/panel.php i know the define is working cos i echo it out earlyer I would like to know how to use an underscore in a define function like this example below. Code: [Select] /** The name of the database for WordPress */ define('DB_NAME', 'Database_name'); /** MySQL database username */ define('DB_USER', 'User_name'); /** MySQL database password */ define('DB_PASSWORD', 'password_here'); /** MySQL hostname */ define('DB_HOST', 'Dtabase_host'); Any help appreciated and thanks in advance. I am trying to use absolute path across my project excluding the domain as of now and I am trying to do it as follows: Code: [Select] define('root', '/php_projects/myproject/'); // The Standard Data $path = "path.php"; $connectvars = "connectvars.php"; // The CSS Styles $reset_css = root . "view/reset.css"; $style_css = root . "view/style.css"; This works so far, the only problem I am having is that it is producing a notice. And my question is, how can I get rid of the notice? The notice is this one: Code: [Select] Notice: Constant root already defined in C:\xampp\htdocs\php_projects\myproject\path.php on line 3 Why does the notice get produced in first place? I never defined it twice, as it states. How come I cannot do this? define('IMG_EXT', array("jpg", "jpeg", "png", "gif", "bmp", "tif"), true); Hello I'm trying to use PHP "for loops" to build a table of 10 rows with 5 columns and I'm sure there's a better way to do this, but the result is the page won't fully load and continually spins its wheel. Here's the code: Code: [Select] $states = array(1 => 'AK','AL','AR','AZ','CA','CO','CT','DC','DE','FL','GA','HI','IA','ID','IL','IN','KS','KY','LA','MA','MD','ME','MI','MN','MO','MS','MT','NC','ND','NE','NH','NJ','NM','NV','NY','OH','OK','OR','OZ','PA','PR','RI','SC','SD','TN','TX','UT','VA','VT','WA','WI' ); <table id="stateCheck"> <?php for ($i = 1; $i <= 10; $i++) { echo '<tr>'; for ($j = 5*$i; $j <= $j+4; $j++) { echo '<td> <input type="checkbox" name="state" value="'.$states[$j].'" /> '.$states[$j].' </td>'; } echo '</tr>'; } ?> <tr> <td> <input type="checkbox" name="state" value="WV" /> WV </td> <td> <input type="checkbox" name="state" value="WY" /> WY </td> </tr> </table> Is it breaking because I'm using arithmetic operators to define the nested for loop? Many thanks |
