PHP - Php Object To Array Then Return Key

hello.

im trying to get some results from a db and all i keep getting is the word ARRAY ??

I want to get all the placeholders that relate to a page.

so if pageID=1 has place holder 1, place holder 2 and place holder 3 it will return 1, 2, 3  etc...

in the db i have

id     pageID    phNumber
1        1           1
2        1           2
3        1           3
etc..


this is the code i have

Code: [Select]
public function find_placeholders($pageID=0){

$sql = "SELECT phNumber FROM ".self::$table_name." WHERE pages_id=".$pageID."";
$result_array = self::find_by_sql($sql);
return $result_array;
}


and on the page i have..

Code: [Select]
<?php echo Placeholders::find_placeholders($pageID); ?>

all i get is Quote

Array



once i solve this problem i will want to use each number in the array to find the content for each.
so if i get 1,2,3

i will try and do some thing like.
foreach placeholder number echo elements

but 1 step at a time

thanks

I am querying a database using pdo but I keep getting an array that returns two results. As you can see from the  array below it returns the id and result and then repeats the result .  I only want the  keys with text to be returned.

Any help would be great.

Code: [Select]
( [0] => Array ( [Ticket_ID] => 2 [0] => 2 [Customer_id] => 1 [1] => 1 [Business_Name] => [2] =>

my database method is
Code: [Select]
    private function queryFetchAllPDO($query) {

        try {
            $this->dataObj->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
            $sth = $this->dataObj->prepare($query);
$sth->execute();
echo"I am here";
$result = $sth->fetchAll();
print_r($result);
   //         $stmt = $this->dataObj->query($query);
//            $stmt->setFetchMode();
//            $result = $stmt->fetchAll();
        } catch (PDOException $e) {

            $e->getMessage();
        }

        return $result;
    }

and the query  method is
Code: [Select]
    private function clieViewHome() {
        //find user id
        $sql = "SELECT Customer_id  FROM customer WHERE Username='" . $this->user . "'";
        $sessAccess = $this->connection->getQueryFetchPDO($sql);
        foreach ($sessAccess as $value) {
            $userID = $value;
        }
        //place into query
        $sql = "SELECT *  FROM tickets WHERE Customer_id ='" . $userID . "'";
        $tableArr = $this->connection->getQueryFetchAllPDO($sql);
         print_r($tableArr);
        foreach ($tableArr as $key => $value) {
            $return .= "<tr>\n";
            foreach ($tableArr[$key] as $value2) {
                $return .="<td>" . $value2 . "</td>\n";
            }
            $return .= "</tr>\n";
        }

       
        return $return;
    }

Hi Guys,

I'm trying the following.. returning an array from a php function to Ajax success but the alert seems to only display undefined.

PHP
Code: [Select]

public function reply()
{
$item_id = $this->uri->segment(3);
$type = $this->uri->segment(4);

if($type == 1){
$data['get_news_item'] = $this->Newsletter_model->get_news_item($item_id);

$test = array( "Paul", "Mike");

return $test;
}
}

AJAX
Code: [Select]


$.ajax({
type: "POST",
url: "<?php echo site_url(); ?>newsletter/reply/"+id+"/"+type,
cache: false,

success: function (data){


alert(data[0]); // So this should display "Paul"?



});


[/code]

Hey guys,

So im building a Content Management System for my A2 project in Computing, and i have a dataBase class. Now, i can return one thing, or do things like inserts however im having a problem returning a list of things such as:

dataBase.class.php

Code: [Select]

          public static function getNYCPost($table, $limit)
{
dataBase::_dbConnect();
if($limit == 0)
{
//debug: echo 'in as 0';
$data = mysql_query("SELECT id, linklabel FROM ".$table." WHERE showing='1' AND id >= 2");
}

if($limit == 1)
{
//debug: echo 'in';
$data = mysql_query("SELECT id, linklabel FROM ". $table ." WHERE showing='1' AND id >= 2 ORDER BY id DESC LIMIT 5");
return $data;
}
}

When i try to do this in the main code:

index.php

Code: [Select]
<?php
  $list = dataBase::getNYCPost($pages,1);
//  echo $list;
  while ($row = mysql_fetch_array($list)) 
{ 
 $pageId = $row["id"];
 $linklabel = $row["linklabel"];
 $menuDisplay .= '<a href="index.php?pid=' . $pid . '">' . $linklabel . '</a><br />';
}
echo $menuDisplay;
  ?>
$list doesnt return anything, the previous method i used in the class was to make a list and an array and put the contents of the query in an array like:

Code: [Select]
list($list[] = $row);
or something i cant quite remember i saw a youtube video tutorial and it worked for them, but it wasnt for me.


If anyone knows how i can return various rows from a database it would be appreciated

Thanks.

I hate array...   😞

So I had a block of code inside my photo-gallery.php script that took the path to my photos directory, and went to that directory, and then read all of the photo filenames into an array.  Then in my HTML, I iterate through this array to display all of the photos for my gallery.

Now I would like to move that code to an included file so multiple scripts can access it and always be working with the same array.

It seems to me that I need to encapsulate my code inside a function?

Then I could call my getPhotoFilesArray back to my callings cript, and use that array for whatever.

I haven't coded PHP in like 4 years and I am struggling to return the entire array back to my caling script.

This is what I have so far...

	function getPhotoFilesArray($photoPath){
	     $photoFiles = array();
	     <code to find corresponding files>
	     $photoFiles gets populated in a loop
	     return $photoFiles;
	}
	

 

Then in my calling script, I have...

	<?php
	     require_once('../../../secure_outside_webroot/config.php');
	     require_once(WEB_ROOT . 'utilities/functions.php');
	     getPhotoFilesArray($photoPath);
	     var_dump($photoFiles);
	

 

I get some error...

	Notice: Undefined variable: phtoFiles in photo-gallery.php line 133 (which is my var_dump).
	

 

<br>

Would appreciate help getting this to work!

SELECT field, (array of values from table 2) FROM $table1 t1 LEFT JOIN $table2 ON t1.id=t2.id

... is something like this possible? (where I return records from t1 in a LEFT JOIN, but also get an array of any of the fields/records from the table 2)

My tree gather function gives me multidimensional array. However i want it to be one dimensional . I was getting one dimensional earlier however i forgot how i got it. Can someone please tell me my mistake

Code
Code: [Select]
<?php
include'config.php';
 function tree_gather($node)   
  {
     
 $sql = "SELECT lchild,rchild FROM tree WHERE parent = '$node'";
    $execsql = mysql_query($sql);
    $array = mysql_fetch_array($execsql);
    
    if(!empty($array['lchild']) || !empty($array['rchild']))
    {
   
      $child[] = $array['lchild'];
      $child[] = $array['rchild'];
      $eh[] = tree_gather($array['lchild']);
      $child = array_merge($child, $eh);
      $eh1[] = tree_gather($array['rchild']);  
      $child =   array_merge($child, $eh1);
     
    } 
     return $child;
  }
$pair = tree_gather(1000000);
echo "<pre>";
print_r($pair);
echo "</pre>";

Hey all I am just now getting around to the newest version of the PHP sdk for Facebook. It seems to use a new array of returned data that I can not seem to be able to parse out what I need and not all other gibberish it has contained inside the array. The array returned looks like this:
 

    Array (
    	[data] => Array (
    		[0] => stdClass Object (
    			[id] => 439676913452345546787863523525
    			[name] => John Doe
    			[picture] => stdClass Object (
    				[data] => stdClass Object (
    					[is_e] =>
    					[url] => https://blah.com....
    				)
    			)
    		)
    		[1] => stdClass Object (
    			[id] => 56594790468026754634524674
    			[name] => Bob Barker
    			[picture] => stdClass Object (
    				[data] => stdClass Object (
    					[is_e] =>
    					[url] => https://blah.com....
    				)
    			)
    		)
    		[2]...etc etc...
    		[paging] => stdClass Object ( 
    			[cursors] => stdClass Object ( 
    				[before] => QWFMmhllXN5JH....Rk52QWc= 
    				[after] => WGHtdnNIwaDlRz....05RNB0E= 
    			) 
    		)
    	)
    )

In the older version of the Facebook SDK I just needed to do something along these lines (below code example is getting the id within the returned array and checking also to make sure it has a value or not):
 

    foreach($theReturnedArray['data'] as $rData) {
      $id = (isset($rData['id']) ? $rData['id'] : null);
      $name = (isset($rData['name']) ? $rData['name'] : null);

      echo $name . ' ' . $id . '<br />';
    } 

in order to get the value that I needed. I have also tried:
 

     foreach($graphObject['data'] as $rData) {
	echo $rData->id + '<br/>';
	echo '======================================<br/>';
     }

and that just gives me 0's for each one it finds..   Now the return has an added stdClass object within the array itself and I am unsure on how to go about getting id, name & picture url from it. Any help would be awesome!

I'm not versed in PHP OOP and I have some code that I need to echo out onto a page. I don't know what the meaning of $ct->something is in this code. Is this an array of some type? How do I echo out the $ct->title onto another page? Use a function call? I just don't know what all of the $ct variables are and how to get to them. Any help is appreciated.
Code: [Select]
function current_theme_info() {
    $themes = get_themes();
    $current_theme = get_current_theme();
    if ( ! isset( $themes[$current_theme] ) ) {
        delete_option( 'current_theme' );
        $current_theme = get_current_theme();
    }
    $ct->name = $current_theme;
    $ct->title = $themes[$current_theme]['Title'];
    $ct->version = $themes[$current_theme]['Version'];
    $ct->parent_theme = $themes[$current_theme]['Parent Theme'];
    $ct->template_dir = $themes[$current_theme]['Template Dir'];
    $ct->stylesheet_dir = $themes[$current_theme]['Stylesheet Dir'];
    $ct->template = $themes[$current_theme]['Template'];
    $ct->stylesheet = $themes[$current_theme]['Stylesheet'];
    $ct->screenshot = $themes[$current_theme]['Screenshot'];
    $ct->description = $themes[$current_theme]['Description'];
    $ct->author = $themes[$current_theme]['Author'];
    $ct->tags = $themes[$current_theme]['Tags'];
    $ct->theme_root = $themes[$current_theme]['Theme Root'];
    $ct->theme_root_uri = $themes[$current_theme]['Theme Root URI'];
    return $ct;
}

I've done pretty much everything I can come up with.
The method itself works fine, if I print_r(); just before returning it, it successfully returns the array.
But once returned, it's empty.
Heres my code:

Any ideas?

Hi! So what I'm trying to do is split a multi dimensional array of strings ( each containing 3 strings inside of 1 array ) so I can write the results to a file.

So say I had a bunch of strings inside 1 array : 

class File {
    function WriteFile ( $filename, $content ) {
        $list = [
            $content
        ];
        $delimiters = File :: checkDelimiter (
            $content, 
            true, 
            false
        );
        $fp = fopen (
            $filename, 'w'
        );
        foreach ( $list as $fields ) {
            $fields = File :: SplitFileByDelimiter (
                $fields, 
                ",", 
                3
            );
            file_put_contents (
                $filename, $fields
            );
        }
        fclose ( $fp );
    }
}

$file-> File :: WriteFile (
    $filepath . $filename, 
    "TEST!, TEST!, TEST!, " . 
    "TEST!, TEST!, TEST!, " . 
    "TEST!, TEST!, TEST!"
);
	

Instead of writing : 

TEST!, TEST!, TEST!, TEST!, TEST!, TEST!, TEST! ,TEST!, TEST!, TEST!
	

to the file in a straight line, it should write it like this : 

TEST!, TEST!, TEST!, 
TEST!, TEST!, TEST!, 
TEST!, TEST!, TEST!
	

Any help is ABSOLUTELY appreciated!

 hello, i seem to be stuck again and this bug is difficult for me to solve.

if(isset($_POST['boards']))
	$boards[] = $_POST['boards'];
$allboards = implode("",$boards[0]);
echo $allboards;

outputs (browser source)...
hello
world

I have a combobox with the "multiple" property.  when two items are selected, the combobox "name" property has an array that passes to the $_POST variable. what i would like is those two words to be displayed on the same line.
I have tried rtrim($var, "\r\n") but that does nothing.

the reason i need them on the same line is because i would change then to "hello, world" and then add them as a mysql query, for example... $query = "SELECT hello, world FROM table...

I'm trying to return to array of letters that bruteForce finally decides upon. However, I can't seem to pass the array to librarySolve.

I'm feeling dumb, any help?

Code: [Select]
function librarySolve($string){
$temp = $this->bruteForce($string, FALSE, 0);
return $temp;
}

function bruteForce($string, $state, $trys){
$base = $string;
$state = $state;
$new_letters = array();

if($trys <= 6000){
$this->new_letters = $this->generateRandomCipher();
$string = preg_replace('/[^a-zA-Z0-9-\s]/', '', $string);

for($a=0;$a<=strlen($string);$a++){
$letter = substr($string, $a, 1);
$pattern = "/[A-Z]/";

if(preg_match($pattern, $letter)!=0){
$new_letter = $this->new_letters[$letter];
} else if(preg_match($pattern, $letter)==0) {
$new_letter = $letter;
}
$decipher .= $new_letter;
}

$word_array = explode(" ", $decipher);

$count = 0;
for($a=0;$a<count($word_array);$a++){
$do = $this->checkWord($word_array[$a]);
if(!empty($do)){
$count++;
}
}

if($count>=2){ $state = TRUE; } else { $state = FALSE; }

if($state==TRUE){
return $this->new_letters;

Hi.
I'm making a registration form, that will put each entered item into $_POST, which will then submit to the same page.
First, I need to has the password with this method:
Code: [Select]
<?php
public function hash_password($password) {
$result = hash(sha512, $password . SALT);
return $result;
}
>?then prepare the entered data for mysql with this method:
Code: [Select]
<?php
public function query_prep($value) {
$result = $this->real_escape_string($value);
if (!$result) {
die("Preparing query failed: " . $this->errno);
}
return $result;
}
?>
However, how can I "validate" the form.
I need to pass the now prepared $_POST array into a loop, that executes the prepare method on each item in the array and then puts it in an array again.
Also, how could I do some kind of function that checks if all required fields were filled, and how I can fail the submission if invalid characters were used.
