    Differences in method writing

    in PHP Coding Help

    Posted

    array and Array are the same, it's case insensitive.  So 1 and 3 are the same.

     

    function a(array $var) { }

     

    This says that a() MUST take an array, and it's an error if you give it something else.

     

    "Catchable fatal error: Argument 1 passed to a() must be an array, string given"

     

    Ah that makes sense! So my 2nd example is stating the $var could be an array, right?

    Can someone explain the difference between the following?

     

    function a(array $var) { }

     

    function a($var = array()) { }

     

    function a(Array $var) { }

     

    I have seen these recently in a script I am modifying, but not 100% sure as to what each one does. Well I know what the middle one does, but am a little confused on the 1st and 3rd one.

     

    Thanks!

    Foreach and For Loop Help

    in PHP Coding Help

    Posted

    Ah gotcha... I just tried it and thats right... I am just trying to show 9 images at a time because of a photo gallery I am working on. Its built to show 9 at a time, but if there is more than 9 then a sliver of the 10th image appears on the page... I just need the script to break at the 9 and then show the next set of 9 images.

    I am working on a photo gallery script in which I need to show 9 images at a time.

     

    Here is my script so far

     

    <?php foreach($pictures->result() as $p): ?>
	<?php for($i = 1; $i <= 9; $i++) { ?>
    		<div class="item">
	     <ul>
	     	 <li><a href="images/gallery/<?=$p->category;?>/<?=$p->photo_name;?>" rel="example1" ><img src="images/gallery/<?=$p->category;?>/thumb_<?=$p->photo_name;?>" alt="#" /></a></li>
	     </ul>
	    </div><!-- end item -->
	<?php } ?>
<?php endforeach; ?>

     

    At the moment the script is showing one image at a time 9 times and for every entry in my database.

     

    I have been battling this for a little while now. Thanks in advance for all of your help!

    SimpleXML Problems

    in PHP Coding Help

    Posted

    I figured out what I was doing wrong.

     

    $xml = new SimpleXMLElement($result);
$ticket_count = (string) $xml['count'];

     

    The first node in the XML was what I was trying to work with and I was going levels in.

    I am trying to retrieve an attribute from a node and I keep getting the error:

    Warning: main() [function.main]: Node no longer exists in /Users/dmonsewicz/Projects/noosemonsewicz/api_stuff/index.php on line 70

     

    PHP Code

    $xml = new SimpleXMLElement($result);
$arr = $xml->tickets->attributes();
echo $arr['count'];

     

    XML

    <tickets count="0" type="array"></tickets>

     

    Any ideas on what I may be doing wrong?

    Creating Order Form

    in PHP Coding Help

    Posted

    I am working on a script for a client of mine that will allow their clients to select photos to order and then will submit the order so that an admin can go back in and look at the order. I am stuck on one thing. I don't know how to go about creating an order id. I need something that is tied to each entry in the database.

     

    I thought about creating the order in the DB and then taking the created rowid and using it as the order id, but that doesn't seem efficient... any ideas?

     

    Thanks in advance

    PHP & CURL

    in PHP Coding Help

    Posted

    I have a CURL app that makes a call to an external webpage on a different site and based upon certain URL params, this webpage will generate a PDF and then send the PDF back to the browser for download.

     

    Is there anyway to grab this PDF with CURL? I have tried it but CURL decodes the file and shows a bunch of weird characters on the screen.

     

    Thanks in advance!

    Apache/Tomcat/PHP/AJP Proxy

    in Apache HTTP Server

    Posted

    I have been banging my head against the wall for days on trying to get my web server optimal to my standards. My company is using a Java based CMS that calls for Tomcat to run on my ubuntu box which uses Apache and AJP Proxy to route everything.

     

    Is there anyway to configure my server to route requests for Tomcat through Tomcat and request for PHP through Apache alone?

    Sorry all it does is print_r the array you pass into it.

     

    updated code

    <?php 
   class Deductible {
       function __construct() {
           mysql_connect('localhost', 'root', 'root')or die(mysql_error());
           mysql_select_db('test')or die(mysql_error());
       }
   
      function carrierSelect($carrier) {
         $results = mysql_query("SELECT DISTINCT manufacturer FROM portal_deductible WHERE carrier = '" . $carrier . "'");
         
         while($row = mysql_fetch_object($results)) {
            $array[] = $row;
         }
         
         return $array;
      }
      
      function errorDisplay($msg) {
        echo '<pre>';
            print_r($msg);
        echo '</pre>';
      }
   }
?>

    Ah! Ok so that problem is fixed :)

     

    Now here is another one

     

    <?php 
    require_once 'phplib.php'; 
    
    $conn = new Deductible();
    $manf = $conn->carrierSelect('att');
    
foreach($manf as $key => $val) {
		    $conn->errorDisplay($manf);
		}
?>

     

    I can't get any results to return when using the following code... but if I do a $conn->errorDisplay($manf) I get everything back... any ideas?

    Before I begin, let me start off by saying that I am a newb when it comes to most things in using classes in PHP, so I apologize for the annoyance factor of simple questions :)

     

    Ok.. I am building out a class for a project I am working on and I am getting some weird errors and I have no idea how to solve them.

     

    <?php 

class Deductible {
    __construct() {
        mysql_connect('localhost', 'root', 'root')or die(mysql_error());
        mysql_select_db('test')or die(mysql_error());
    }

	function carrierSelect($carrier) {
		$results = mysql_query("SELECT DISTINCT manufacturer FROM portal_deductible WHERE carrier = '" . $carrier . "'");
		return mysql_fetch_object($results);
	}
}
?>

     

    Error Message:

    Parse error: syntax error, unexpected T_STRING, expecting T_FUNCTION in /Applications/MAMP/htdocs/class/phplib.php on line 4

     

    If I change my code to the following

    <?php
class Deductible {
    function Deductible() {
        mysql_connect('localhost', 'root', 'root')or die(mysql_error());
        mysql_select_db('test')or die(mysql_error());
    }

	function carrierSelect($carrier) {
		$results = mysql_query("SELECT DISTINCT manufacturer FROM portal_deductible WHERE carrier = '" . $carrier . "'", $this->Deductible());
		return mysql_fetch_object($results);
	}
}
?>

     

    I now get this error:

    Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in /Applications/MAMP/htdocs/class/phplib.php  on line 9

     

    Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource in /Applications/MAMP/htdocs/class/phplib.php on line 10

     

    Any ideas on why this is happening?

     

    Thanks!

    string offset help

    in PHP Coding Help

    Posted

    I have the following function:

     

    function string_into_parts($text, $length=45) {
            $text = strval(trim($text));
            $array = array();
            $counter = 0;
            if(strlen($text) > $length) {
                for($i=0;$text[$length+$i]!=" ";$i++) { //line 67
                    if(!$text[$length+$i]) { //line 68
                        return $text;
                    }
                }
                $array['firstHalf'] = trim(substr($text,0,$length+$i));
                $array['secondHalf'] = trim(substr($text,$length+$i));
            } else {
                $array['firstHalf'] = $text;
                $array['secondHalf'] = '';
            }
            return $array;
    }

     

    but if you run it on a string that contains an individual number, IE: it broke into 2 pieces, the script fails and I receive the Uninitialized string offset error message. The script fails at lines 67 & 68.

     

    Anyone know why this could be failing?

     

    Thanks in advance!

    I have a function that takes a string and splits it up into two parts... well I keep running into the issue of Uninitialized String Offest: 52... but it only happens when the string is more than the specified length..

     

    function string_into_parts($text, $length=45) {
            $text = trim($text);
            $array = array();
            if(strlen($text) > $length) {
                for($i=0;$text[$length+$i]!=" ";$i++) {
                    if(!$text[$length+$i]) {
                        return $text;
                    }
                }
                $array['firstHalf'] = trim(substr($text,0,$length+$i));
                $array['secondHalf'] = trim(substr($text,$length+$i));
            } else {

    CONCAT query only returns a few results

    in MySQL Help

    Posted

    I have a query that I am writing to convert a query statement into a JSON string, but when it runs it only returns 14 rows and a little bit of the 15th row...

     

    Any ideas on why this is?

     

    SELECT
     CONCAT("[",
          GROUP_CONCAT(
               CONCAT("{'rowid':'",rowid,"'"),
		 CONCAT(",'carrier':'",carrier,"'"),
               CONCAT(",'manufacturer':'",manufacturer,"'"),
		 CONCAT(",'model':'",model),"'}"
          )
     ,"]") 
AS json FROM portal_deductible
