PHP - Accessing Variables In A Required Folder When Using Ajax
I have a file, test.php. It has a require statement to include line.php. Now on normal load, I can access the variables set in test.php in line.php.
However, I also have an automated reload of line.php using AJAX, where I send a request to access the file and it outputs the same information. HOWEVER, in this case, the variables set in test.php can no longer be access :s .. why is that? I haven't set any data to be passed in the request, but I assume this doesn't have to be done. Similar TutorialsIs there any way to access a variable that is not assigned until further down the page eg: echo $myname; $myname = 'batman'; // clearly my real name which is why I am so poor at coding Thanks Hi guys, I am trying something fairly simple but I'm not sure if this would be a good practice. Basically I am using a big class called CommonLibrary that holds common functions as methods and common variables as static variables. But I have some variables here and there like $allAlphabet = range ('a' , 'z'), that cannot be declared as a property because it gives me a parse error. I don't want to call an object for this class because instancing it is of no use. Values will never change with regards to instances. So the next best thing that I tried was declaring all static variables first, and then changing thei property values inside the class __construct with self::$variable = 'somevalue', and then using this code below to assign values to the empty static variables. $dummyObject = new CommonLibrary; unset($dummyObject); echo CommonLibrary::$staticVariable; // This property is NULL before the constructer is triggered. Anyone recommend any better ways of doing this? Thanks in advance!
I have a php file with a bunch of variables declared. I now need a function to put data on a separate page that pulls variables from the required page.
<?php
function getplayer($position)
{ // start function
//$new_position = "$" . $position;
$new_position = $position;
$file = "their.php";
require "$file";
//echo $qb1; this displays the name John Doe...as $qb1 is declared in the required file
$db_select_their = "bschultz_their";
$servername = "localhost";
$username = "user";
$password = "pass";
$dbname = "db_name";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM (select number as position_number, name as position_name, pronunciation as position_pronunciation, pos as position_pos, height as position_height, weight as position_weight, year as position_year, city as position_city, state as position_state, notes as position_notes FROM $db_select_their WHERE name = '$new_position') as position";
//$sql = "SELECT * FROM bschultz_their WHERE name = $new_position";
echo $sql; //exit;
/*
this displays this text... SELECT * FROM (select number as position_number, name as position_name, pronunciation as position_pronunciation, pos as position_pos, height as position_height, weight as position_weight, year as position_year, city as position_city, state as position_state, notes as position_notes FROM bschultz_their WHERE name = '') as position
The name is empty
*/
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "#: " . $position_number . " - Name: " . $position_name . "";
}
} else {
echo "0 results";
}
} // end function
getplayer("${$qb1}");
$conn->close();
?>

I got this script: But it give me error, file_get_contents cannot open stream. I need to add the FTP connection with user/pass paramaters. then look in set http url, to get the file contents(images) and transfer to ftp server location. Can Anyone take alook and tell me if I am going down the right path and how to get there. Please Code: [Select] function postToHost($host, $port, $path, $postdata = array(), $filedata = array()) { $data = ""; $boundary = "---------------------".substr(md5(rand(0,32000)),0,10); $fp = fsockopen($host, $port); fputs($fp, "POST $path HTTP/1.0\n"); fputs($fp, "Host: $host\n"); fputs($fp, "Content-type: multipart/form-data; boundary=".$boundary."\n"); // Ab dieser Stelle sammeln wir erstmal alle Daten in einem String // Sammeln der POST Daten foreach($postdata as $key => $val){ $data .= "--$boundary\n"; $data .= "Content-Disposition: form-data; name=\"".$key."\"\n\n".$val."\n"; } // Sammeln der FILE Daten if($filedata) { $data .= "--$boundary\n"; $data .= "Content-Disposition: form-data; name=\"".$filedata['name']."\"; filename=\"".$filedata['name']."\"\n"; $data .= "Content-Type: ".$filedata['type']."\n"; $data .= "Content-Transfer-Encoding: binary\n\n"; $data .= $filedata['data']."\n"; $data .= "--$boundary--\n"; } // Senden aller Informationen fputs($fp, "Content-length: ".strlen($data)."\n\n"); fputs($fp, $data); // Auslesen der Antwort while(!feof($fp)) { $res .= fread($fp, 1); } fclose($fp); return $res; } $postdata = array('var1'=>'today', 'var2'=>'yesterday'); $filedata = array( 'type' => 'image/png', 'data' => file_get_contents('http://xxx/tdr-images/images/mapping/dynamic/deals/spot_map') ); echo '<pre>'.postToHost ("localhost", 80, "/test3.php", $postdata, $filedata).'</pre>'; I want to copy everything in templates/blue to the folder code/ However: shell_exec("cp -r 'templates/blue' 'code'"); Creates a folder called blue inside code. I tried cp -r 'templates/blue/*' 'code', but that didn't do anything. Any ideas? Right now I redirect to index page after I delete a record. However I am looking to make it so that I can delete a record without redirecting the page. I know this can be accomplised using Ajax. I have spent countless hours before trying to make it work, but it did not work.
So here is a basic setup I created. Can you please update it with ajax code so that I can see how it's done properly?
<!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8"> <title>Home Page</title> </head> <body> <div class="record" > <a href="record.php?id=<?php echo $record_id ?>"><?php echo $record_name; ?></a> <div class="delete-record"> <a href="delete.php">Delete Record</a> </div> </div> </body> </html> Edited by man5, 18 August 2014 - 08:55 PM. Now I'm having this strange issue with my website I'm currently working on a tester system and I've encountered a problem that I'm unable to find the issue, tho I'm thinking my ajax php part of the script to be the thing causing it even tho it seems strange that it would cause it. The first part which is connected to where the problem occurs is the echo"<form>"; and from there, It should take you to index.php?page=tester&select=answer, now that is where it in the browser goes there tho it still shows the page stuff from the last page which is index.php?page=tester&select=applications, so it's like showing both &select=answer and &select=applications on the same page. <?php $q=$_GET["q"]; include'../config/connection.php'; $result = mysql_query("SELECT * FROM applications WHERE id = '$q'"); echo "<center><table border='1'> <tr> <th>Account Name</th> <th>Character Name</th> <th>Gender</th> <th>Skin Color</th> </tr>"; $row = mysql_fetch_array($result); echo "<tr>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['charactername'] . "</td>"; echo "<td>" . $row['gender'] . "</td>"; echo "<td>" . $row['race'] . "</td>"; echo "</tr></table></center>"; echo"<br/>"; echo"<table><tr> <th>Description</th> <th>Metagaming</th> <th>Powergaming</th></tr>"; echo"<tr>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['description']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['mg']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['pg']."</textarea></td>"; echo"</tr></table><table><br/><center><h1>Answer</h1><br/><form action='index.php?page=tester&select=answer' method='post'>"; echo"<textarea name='why' style='height:10em; width:60em;'></textarea><br/>"; echo"<input type='submit' name='answer' value='Accept' /><a/>"; echo"<input type='submit' name='answer' value='Decline' /></center>"; echo"<input type='hidden' name='id' value='$q'/>"; echo"</form></table>"; ?> Now on &select=answer it included a page which the script of that include consist of the stuff below, it outputs that the query was successfully, and all that. <? if(!empty($_POST['why'])) { $why = mysql_real_escape_string($_POST['why']); $answer = trim($_POST['answer']); $id = $_POST['id']; if($answer == "Accept") { $query1 = mysql_query("UPDATE characters SET accepted = '1' WHERE id = '".$id."'"); echo"Successfully accepted"; $answer = 1; } elseif($answer == "Decline") { echo"Successfully declined"; $answer = 0; } $query = mysql_query("UPDATE applications SET answer = '$why' AND tester = '".$_COOKIE['Username']."' AND accepted = '$answer' AND answered = '1' WHERE cid = '".$id."'") or die('Could not connect: ' . mysql_error()); if($query) { echo"<br/>Query went through without problems"; header("Refresh: 5;url=index.php?page=tester"); } } ?> This is the ajax part javascript of it which gets the information for index.php?page=tester&select=applications Code: [Select] <script type="text/javascript"> function showApplication(str) { if (str==""||str==0) { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","tester/applications.php?q="+str,true); xmlhttp.send(); } </script>If you need any more information feel free to ask for it. Thanks in advance. Hello, I've been trying this for hours now, looking at different examples and trying to change them to work for me, but with no luck... This is what I am trying to do: I have a simple form with: - 1 input field, where I can enter a number - 1 Submit Button When I enter a number into the field and click submit, I want that number to be send to the php file that is in the ajax call, then the script will take that number and run a bunch of queries and then return a new number. I want that new number to be used to call the php script via ajax again, until no number is returned, or something else is returned like the word "done" or something like that, at which point is simply makes an alert or populated a div with a message... The point is, that depending on the number entered it could take up to an hour to complete ALL the queries, so I want the script that is called to only run a fixed amount of queries at a time and then return the number it is currently at (+1), so that it can continue with the next number when it is called again. I would like to use jquery, but could also be any other way, as long as I get this to work. I already have the php script completed that needs to be called by the ajax, it returns a single number when being called. Thank you, vb HEy Guys Here is a snippet of an array: SimpleXMLElement Object ( [report1] => SimpleXMLElement Object ( [ReportHost] => Array ( => SimpleXMLElement Object ( [HostName] => 192.168.2.34 [startTime] => Thu Dec 17 13:58:49 2009 [stopTime] => Thu Dec 17 15:13:13 2009 [netbios_name] => (unknown) [mac_addr] => (unknown) [dns_name] => (unknown) [os_name] => (unknown) [num_ports] => 2 [num_lo] => 0 [num_med] => 0 [num_hi] => 0 [ReportItem] => Array which is printed using print_r($a) now how can i access [HostName] => 192.168.2.34 in the $a array?? Thanks in advance I am a part of an institue which has internal web pages. It also provides me with my web space with php servers. Now I know those internal web pages are available to the server. I want a code that can fetch those web pages and display it in my web space. And whatever forms i fill or links i click it should do those on internal page and again return the new web page. Hi guys, I have xml that looks like: <item> <title></title> <link></link> <description></description> <dc:date>2011-02-27T16:42:31-05:00</dc:date> </item> I can access title, link, and description just fine. But how do I access a tag that has a colon? I tried this: Code: [Select] $x = new SimpleXmlElement($content); $entry = $x->item; $entry->children('dc', true)->date; Thanks for looking. LR If $result contains the result of mysql_query, a select count distinct query, how do I access the count? I've tried $result[0] to no avail and $result only returns the resource #. does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

That page does in fact exist, but I think the issue might be something to do with a redirection. The site owner apparently clicked on something in the admin section (possibly https or something similar) but what can I do to avoid this issue without having to re install everything? Thanks, Neil I have the following code in zend: Code: [Select] $arrErrors=array(); if (!empty($this->post['submit'])) { // Each time theres an error, add an error message to the error array // using the field name as the key. if (empty($this->post['client_name'])) $arrErrors['client_name'] = "Please Enter Client's name as it appears in the carrier software"; } if i set $this->view->arrErrors=$arrErrors in the controller, Can I access it as $this->arrErrors['client_name'] in the view? Hi all, I am still trying to figure what went wrong. It doesn't work over here. The error shown was the {else} command else { echo '<p class="error">There was a problem accessing your profile.</p>'; } I have attached my 4 sql tables for reference. Appreciate any advices....

echo $result["fromAddress"]["phone"]; Unfortunately I must have fallen asleep during the array lesson in PHP class ? Thank you. So basically I'm using PHP to solve a math problem for me. The user puts in a few parameters and the program runs those numbers through the algorithm and spits out a bunch of xy coordinates. I'm using the PHP SELF method to retrieve the user input. This all works fine, but it's afterwords that I run into problems. I create a drop down menu of all the x values and I want the user to be able to choose any x value they wish and to have the corresponding y value be displayed. The problem is that I have to use another POST command for this and when I do, it wipes out all the computed data. Of course the y-value is never displayed, and there lies the problem. I'm sure there are many ways to get around this, but I could not find one out myself. Anyone have any ideas? Is it possible to have a class access another class it its parent directory without using a fully qualified name? While the following script is not valid, it is how I would have thought it would be done should it be possible. If it is not possible, I expect there is a good reason why one would not want to do so, and would appreciate your thoughts why that is so. Thanks

Hey everyone, I'm creating a website which requires users to login. I didn't want to have to do my own crypto, so I basically created it with Wordpress. I'm at the point where I don't want to use Wordpress for the whole site--just the login system. So I was wondering how I can piggyback off the user management system of Wordpress while using my own script for the rest of the site. I know that Wordpress ends up storing passwords in the database as HMACs, for what that's worth. Thank you, Ryan |
