PHP - Why Get Works Before Being Declared In Variable?
I don't understand why "if(isSet($_GET['sid'])) " works before it is declared in the variable name(" $name = $_GET['sid'];"). 1. How does php store the date in this get statement? 2. Is GET an array?
Code: [Select] if(isSet($_GET['sid'])) { echo "<h2>Exercise</h2>"; $name = $_GET['sid']; $timein = time(); $quest=1; $nextquest=2; } else { echo "<h2>Enter Student Number:</h2>"; $quest=0; $nextquest=0; } Similar TutorialsI have a template page that opens with a GO click from a drop-down in a different page. The variable is being passed through to the URL and in the GET statement. However, my PHP code is producing the following error: Quote Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in /data/23/2/100/53/2263053/user/2487001/htdocs/myalaskacenter/events/venues/test_venues-results.php on line 52 .

Below is the code i'm working with: Gooday Coders. Im using php 5.4 with xampp 1.8. Each time I run this script "add+stock.php", the script jumps to line 240 saying header is already defined. Thus referring to the session headers. What can I do to get rid of these header errors?

Hi, Basically I am going to give a short description to my problem with pseduo and comments (-->), there is too much to paste all my code he basically include(config.php) --> database connection include(global.php) --> class is instantiated here as $p ($p is GLOBAL) --> I print_r the $p value here, and it shows (debugging) switch() case x: include file.php; break; --> but when I try to access it or print_r it here (here being within the file.php), via the file that has been included above "include file.php", it does not see it. I have to re-declare the $p variable with the class, within the included file. any tips as how to solve this please; I dont see why it wouldnt see it, since all the file is that I am including is an HTML file with a few PHP lines, which checks if a user has permission: if(!$p->check()) redirect("index.php"); Hi all, I have this structure of two functions: function get_string_between($string, $start, $end){ $string = " ".$string; $ini = strpos($string,$start); if ($ini == 0) return ""; $ini += strlen($start); $len = strpos($string,$end,$ini) - $ini; return substr($string,$ini,$len); } function normaliza($text){ function entre($string, $start, $end){ $string = " ".$string; $ini = strpos($string,$start); if ($ini == 0) return ""; $ini += strlen($start); $len = strpos($string,$end,$ini) - $ini; return substr($string,$ini,$len); } foreach (count_chars($text, 1) as $i => $val) { if(chr($i)=='<'){ $totaltag = $val; } } for($u=0; $u <= $totaltag; $u++){ $parsed = entre($text, "<", ">"); $text = str_replace('<'.$parsed.'>',"",$text); } return $text; } The I passed a text named $data throught both functions and I got the correct return: $status = get_string_between($data, 'Inativo', 'CNPJ'); $status = normaliza($status); echo $status.' '; Just after, I passed the same folowing text throught the same both functions: $cnpj = get_string_between($data, 'CNPJ', 'Grau'); $cnpj = normaliza($status); echo $cnpj.' '; And I got this error: Cannot redeclare entre() (previously declared in C:\Users\entidade.php:47) in C:\Users\entidade.php on line 47 Why? I thougth this kind strange because it didin't gave the same error for the function get_string_between. Thanks danilo jr. Dear all, I am new to the forums, with a hope that somebody can point me in the right direction. I am coding a new photo website, and am doing it with PHP to maximize my flexibility. In essence I want to have a set of gallery folder on the server, and the site reads off these folders and automatically generates the required galleries. My PHP code is below, along with a detail of the exact problem: <?php $main = "Collections/"; # Location of galleries $big = "Large/"; # Location of big versions (subdir within each gallery) $i = 0; #Gallery Iterator #Searching for galleries & Checking only for directories (save them im $galleries array) $tempgalleries = scandir($main); foreach ($tempgalleries as $gallery_iterate) { if (!is_dir($gallery_iterate)) { $galleries[]=$gallery_iterate; } } #Iterating galleries. Collecting each gallery's images (saving in $GalleryImages.$i). This creates an image array for each $galleries[$i] for($i=0; $i<=sizeof($galleries)-1; $i++) { #Making the title nice (from the the directory names) $GalleryTitles[$i] = str_replace('_',' ', $galleries[$i]);; $temp_gallery = opendir($main.$galleries[$i]); #Checking for Images and storing in array if valid while (false !== ($image = readdir($temp_gallery))) { if ($image != "." && $image != ".." && $image != rtrim($big,"/") && strstr($image,'.jpg')) { ${$GalleryImages_.$i}[] = $image; } } #Sorting the images numerically natsort(${$GalleryImages_.$i}); closedir($temp_gallery); } #Better location for the buttons!! #Printing the galleries and all the html required for naming, separation, etc.. This is also an iteration for($i=0; $i<=sizeof($galleries)-1; $i++) { echo('<div class="galleries_hidden" id="gallery_'.$i.'"><hr><br><div class="Gallery_Title"><b><i><big>'.$GalleryTitles[$i].'</big></i></b></div><br>'); $folder=$galleries[$i]; foreach(${$GalleryImages_.$i} as $thumb_image) { echo '<a href="'.$main . $folder .'/'. $big . 'large_'. $thumb_image . '" rel="lightbox['.$folder.']" title="'.$folder.'"><img src="' . $main . $folder .'/'. $thumb_image. '" alt="'.$folder.'" class="Gallery_Image" /></a>'; } echo('</div>'); } #Making the buttons to cycle the galleries for($i=0; $i<sizeof($galleries); $i++) { echo('<input type="button" id="gallery_'.$i.'" value="Show '.$GalleryTitles[$i].'" onclick="showgallery(');echo("'gallery_".$i."');");echo('" /><br><br>'); } ?> I have managed to make each aspect work, exept one. The last portion, as commented: #Making the buttons to cycle the galleries for($i=0; $i<sizeof($galleries); $i++) { echo('<input type="button" id="gallery_'.$i.'" value="Show '.$GalleryTitles[$i].'" onclick="showgallery(');echo("'gallery_".$i."');");echo('" /><br><br>'); } This piece of code generates buttons which shows one gallery, and hides the rest. This is done by changing the classes of the divs from "galleries_visible" to "galleries_hidden", as applicable. This is done using a javascript declared in the header as follows: Code: [Select] <script type="text/javascript"> function showgallery(id) { var divall = document.getElementsByTagName("div"); var i=0; for (i=0;i<divall.length;i++) { if(divall[i].className == "galleries_visible") { divall[i].className = "galleries_hidden"; } var showdiv = document.getElementById(id); showdiv.className = "galleries_visible"; return false; } </script> When I have the button-generating php code below the gallery-generating php code, then the javascript seems to work, by showing and hiding respective galleries. These galleries and their litebox viewer all work normally. However, when putting the button-creator php above the gallery-generator php, then the buttons appear as normal, and the javascript runs, but it cannot find the div with the id it searches for: Code: [Select] var showdiv = document.getElementById(id); showdiv.className = "galleries_visible"; I am confused. The PHP code makes several arrays which stores all the file and folder information, and these arrays are read by the button-generator irrespective of its position (I know this because the buttons are generated based on the content of non-empty arrays). Why can't the javascript change the gallery-containing divs when they are below the button-containing div? Any help is greatly appreciated, I just cant seem to find whats wrong! Kind regards, Frederik I'm receiving a cannot redeclare function error. I have a functions.php pack that I only require_once once. require_once 'functions.php'; require_once 'classes.php'; A little further into the code I conditionally require another php file. require_once 'dataentry.php'; It appears that when the require_once 'dataentry.php' line is hit, I receive this redeclare error. I do not call any include or require in dataentry.php. The first function in my function pack throws this error, and when I comment it out, the next function throws the error. Im appalled as to the reasoning for this error. Any Thoughts? Hi All, My appologies in advance. I am pretty sure that this has probably been answered before by someone...but for the life of me I carn't find the answer in any forums. My basic question is this. Can you create an object at the beginning of a script, and then call its methods from within functions? I have coded the following: <?php ///import classes to use require "booking_form_gui.php"; $booking = new booking_form_gui(); function _booking_form($form_state){ ///$booking = new booking_form_gui(); return $booking -> date_selection(); <----------this line causes the error I guess } The problem is that when I run this code, I get an error message similar to the following: Fatal error: Call to a member function date_selection() on a non-object in /var/www/drupal_6/sites/default/modules/booking_system/booking_form/booking_form.module on line 127 Anyone any ideas how I could get round this? Thanks, Mark. Newb here trying to build a form that works with ints to count how many red shirts die in a classic episode of star trek (exercise to get better with forms and ints). I have an error which reads as '7 Error message: Undefined index: rsTot'. I have tried a few things and read that setting it(casting it?) as a float was the safest way to work with the int, however each thing i've attempted results in some sort of error so after a day of reading and trying i'm very confused and hoping for an answer I can understand here.
I have read through stackOverflow for an answer but not seen one which i can understand and apply that speaks to the problem i'm having of initially entering and process a number as an int which i can later do some math on.

Edited by Chezshire, 25 May 2014 - 08:10 AM. Hello All,
I have designed a small php module Which has more than 80 .php files. I want to give the access level for all those files through a global access.php file. But i am not getting how it can be developed. I made a table in database which has all the scripts name. When those are checked value 1 it has to be visible for those users who come under a perticular position like MD, CEO, Sales Manager etc. Here is my table structure
script.JPG 20.61KB
0 downloads
and i tried doing like this
if($_SESSION['pos']=='admin')
{
echo "<h1> SORRY YOU DONT HAVE ACCESS </h1>";
}
else
{

Fatal error: Cannot redeclare limitatexto() (previously declared in funciones.php:4) in funciones.php on line 12 <?php function limitatexto( $texto, $limite ) - Line 4 { if( strlen($texto)>$limite ) { $texto = substr( $texto,0,$limite ); } return $texto; } Line 12 Hello all. I am very new to PHP, and I am not sure where to look or what I'm looking for in my current assignment. My task is to take in two numbers between 0-100. Once I take in that number, it should state beside it "The __ was accepted." The program should not accept any numbers greater than 100 or any characters. Once I do this, I must take a second number and do a similar thing. Finally, I must have a statement show up at the bottom stating which number is greater. Essentially, I need help in determining what I should use to place parameters, and how I can keep the program from echo ing any statement until input has been taken and tested for parameters. Any help you can provide will be greatly appreciated! I am trying to allow the user to update a variable he chooses by radio buttons, which they will then input text into a box, and submit, to change some attributes. I really need some help here. It works just fine until I add the second layer of variables on top of it, and I can't find the answer to this question anywhere. <?PHP require('connect.php'); ?> <form action ='' method='post'> <select name="id"> <?php $extract = mysql_query("SELECT * FROM cars"); while($row=mysql_fetch_assoc($extract)){ $id = $row['id']; $make= $row['make']; $model= $row['model']; $year= $row['year']; $color= $row['color']; echo "<option value=$id>$color $year $make $model</option> ";}?> </select> Which attribute would you like to change?<br /> <input type="radio" name="getchanged" value="make"/>Make<br /> <input type="radio" name="getchanged" value="model"/>Model<br /> <input type="radio" name="getchanged" value="year" />Year<br /> <input type="radio" name="getchanged" value="color" />Color<br /><br /> <br /><input type='text' value='' name='tochange'> <input type='submit' value='Change' name='submit'> </form> //This is where I need help... <?PHP if(isset($_POST['submit'])&&($_POST['tochange'])){ mysql_query(" UPDATE cars SET '$_POST[getchanged]'='$_POST[tochange]' where id = '$_POST[id]' ");}?> My login script stores the user's login name as $_SESSION[ 'name'] on login. For some unapparent reason, i'm getting errors stating that $user and $priv are undefined variables, though I've attempted to define $user as being equal to $_SESSION['name'], using $user to look up the the user's privilege level (stored as the su column ) in the SQL table, and then where the result of the sql query is $priv which is then evaluated in an if statement. I can't seem to figure out why this might not be working. The code I'm using:
<?php
session_start();
function verify() {
//verify that the user is logged in via the login page. Session_start has already been called.
if (!isset($_SESSION['loggedin'])) {
header('Location: /index.html');
exit;
}
//if user is logged in, we then lookup necessary privleges. $_SESSION['name'] was written with the login name upon login. Privleges // are written in db as a single-digit integer of of 0 for users, 1 for administrators, and 2 for special users.
$user === $_SESSION['name'];
//Connect to Databse
$link = mysqli_connect("127.0.0.1", "database user", "password", "database");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
//SQL Statement to lookup privlege information.
if ($result = mysqli_query($link, "SELECT su FROM accounts WHERE username = $user", MYSQLI_STORE_RESULT)) {
//LOOP TO CYCLE THROUGH SQL RESULTS AND STORE Privlege information as vairable $priv.
while ($row = $result->fetch_assoc()) {
$priv === $row["su"];
}
}
// close SQL connection.
mysqli_close($link);
// Verify privleges and take action. Only a privlege of "1" is allowed to view this page. A privlege of "2" indicates special
//accounts used in other scripts that have certain indermediate additional functions, but are not trusted administrators.
if ($priv !== 1) {
echo $_SESSION['name'];
echo "you have privlege level of $priv";
echo "<br>";
echo 'Your account does not have the privleges necessary to view this page';
exit;
}
}
verify();
?>
I have just re-installed Xampp and suddenly my sites are now displaying lots of: Notice: Use of undefined constant name - assumed 'name' in ... Notice: Use of undefined constant price - assumed 'price' in ... this is an example of the line its refering too: $defineProducts[1001] = array(name=>'This is a product', price=>123); 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? Hello everyone, I can get Test 2 to successfully operate the if statement using a variable variable. But when I try the same method using a session variable (Test 1) the if statement is not executed. Please could you tell me why the if statement in Test 1 is not being executed? Code: [Select] <?php # TEST 1 $_SESSION[test_variable] = "abcd"; $session_variable_name = "_SESSION[test_variable]"; if ($$session_variable_name == "abcd") { echo "<br>line 373, abcd<br>"; } # TEST 2 $test_variable = "efgh"; $test_variable_name = "test_variable"; if ($$test_variable_name == "efgh") { echo "<br>line 379, efgh<br>"; } ?> Many thanks, Stu I have a form that creates rows of data input textboxes depending on a user input number of things. I have a naming convention for all these textboxes that basically just keeps incrementing a number suffix for each row. All this is working fine. My problem is I need to get the data inserted into this table of textboxes into an array. Here's my code where I attempt to to this (it does not work): Code: [Select] $temp = $_SESSION['Num_Part']; $count = 1; while ($count <= $temp){ $temp2[$count] = "'Participant_P".$count."'"; //echo $temp2[$count]."<br/>"; $temp3[$count]=$_POST[$temp2[$count]]; //here's the problem $temp4[$count] = "'Result_P".$count."'"; $temp5[$count]=$_POST[$temp4[$count]]; //here's the problem //echo $temp4[$count]."<br/>"; $count++; } The problem is that the $_POST does not work with the variable in the argument position - even though the argument is formatted with single quotes. Can a variable be used in a POST argument and if so what is the correct syntax? If not, is there some other simple solution to harvest the data into an array. I understand I can harvest by explicitly accessing each key in the post assoc array. But this could be dozens of rows of input fields. Thanks in advance for your help here. I couldn't find anything online re this topic. hi all, I have an language pack for example: languages/en.php: Code: [Select] $en['mail']['letter closing'] = "regards,\n your friend!"; and in my config: Code: [Select] $language = "en"; $include_language = @include("languages/".$language.".php"); if(!($include_language)) { $try_default_language = @include("languages/nl.php"); if(!($try_default_language)) { echo "kan de taalpakket niet vinden<br>"; echo "Could not find the language pack.<br>"; echo "example on error: ".$test." shows nothing"; exit; } } In my function I want to include the language pack for example i have $language = 'en' so I want to include $en['general']['letter closing'] I will do this: Code: [Select] global $language,${$language}['general']; But that gives an error unexpected '[' blah blah. How can i call the variable variable array in the valid php way? Probably something simple but I have searched high and low and can't figure this one out. I have a variable that is of the datetime format. I have another variable that is of the time format. I need to add them together. Example: $var1 = 2012-02-24 06:38:22 $var2 = 02:00:00 $var3 = $var1 + $var2 = 2012-02-24 08:38:22 Thanks for the help! |
