PHP - Can't Retrieve Admin Status From Sql Retrieval.

I'm going bananas with one of those issues where it looks like everything is right but the code won't work.  I've included a script below that fetches data from a database and creates a drop down menu.  I'm trying to use a field called "gone" and enter 'gone' in that field when I want to delete the row but be able to retrieve it by making the field empty.  There is something in the WHERE clause of my sql that is screwing things up.  I get nothing retrieved with any of the WHERE clauses below.  Interestingly, when I take the where clause out completely, I get the rows that have no 'gone' in them.

The code is below.  None of the following in the included code get me a result.  All of them return nothing.  I also don't get any errors. Just nothing.

WHERE gone != 'gone'

WHERE gone <> 'gone'

WHERE gone = ''

WHERE gone = 'gone'

Without the WHERE clause it runs fine.

As a work around I tried using

if($row['gone'] == 'gone')  { continue;}

In the while.. function at the end of the file to bypass rows with 'gone' in the field.  It also stopped the script.

Here's my code:

<?php // person_selectall.php

/** Create new pdo object */

require 'Db.php';

//$sql = "SELECT person_id, fname, lname FROM Persons";
$sql = "SELECT * FROM Persons WHERE gone = ''";

$stmt = $pdo->prepare($sql);
$stmt->execute();

echo "<p><select class=\"select-field\" name=\"person_id\" >\n";

while ($row = $stmt->fetch()) {  
    
    $name = $row['fname'] . ' ' . $row['lname'];
    echo "<option value=\"" . $row['person_id'] . "\">" . $name . "</option>\n";
    
    }
    
echo "</select>";

?>

 

Hello, 

Hello,

I am writing a data retrieval script, in order to print data stored in a DB. For some reason the script does not work..

More details below..

Code: [Select]
the form that calls the initiator script..

<form method='get' action="init.Get.php">
<div><input type="submit" name="get" value="See Data"></div>   
</form>

Code: [Select]
the initiator script

<?php
include 'dataGet.class.php';
$data= new getData();
$data= getData($name, $email, $text);
?>

Code: [Select]
my class..

<?php
class getData {
    private $name;
    private $email;
    private $text;
    
    function __construct(){
        $this->host = 'localhost';
        $this->uname = 'root';
        $this->pword = '1111';
        $this->dbname = 'teststorage';
        $this->dbtable = 'userData';
        }
    function getData($name, $email, $text){
        $this->dbconnect = mysql_connect($this->host, $this->uname, $this->pword);
        if (!$this->dbconnect) die("Connection Unable " . mysql_error());
        
        mysql_select_db($this->dbname);
        $sql_query = "SELECT * FROM $this->dbtable ";
        $result = mysql_query($sql_query);
        
        if ($result){
            echo $result;
        }
        else{
            echo "Retrieval Unsuccesful";
        }
        mysql_close($sql_query);
    }
}

?>

Can someone please tell me what am I doing wrong?

Thank you in advance.

Hi I am currently making a site where users can upload second hand books for sale, I have everything working as i wish apart from i am having trouble creating a account page where users can review the books they have posted.

so far i use the following code to bring view a the data associated with an uploaded book based on its id

Code: [Select]
  public static function getById( $id ) {
    $conn = new PDO( DB_DSN, DB_USERNAME, DB_PASSWORD );
    $sql = "SELECT * FROM books WHERE id = :id";
    $st = $conn->prepare( $sql );
    $st->bindValue( ":id", $id, PDO::PARAM_INT );
    $st->execute();
    $row = $st->fetch();
    $conn = null;
    if ( $row ) return new Book( $row );
  }

I think i can use a similar function for my user account however, each book entered by a user has their member id attached to it, which is gained from there id in the members table which in turn is stored in $_SESSION['id']. My question is, is there a way to rework the code above to have something like select * where member_id = $_SESSION['id']. I have tried a few things and get stuck manly due to the fact i dont know what to replace the current :id with.

Thanks in advance, i hope i explained it well enough for you lot to understand.

Hello everyone,

Let's say I am connecting to a database using PDO (I am excluding prepared statements for the sake of simplicity):
try 
{
$conn = new PDO('mysql:host=localhost;dbname=cms', 'root', 'password');
$result = $conn->query('SELECT * FROM news');
} 
catch (PDOException $e) 
{
echo 'Error: '.$e->getMessage();
exit;
}


So far I been using the following to manipulate the data in object form:
while ($row = $result->fetchObject()) {
echo $row->title;
echo $row->text;
}

My question is, is there a better way?

What is the foreach code equivalent to that? I have had no luck keeping the data in object form using foreach statements.

Which method is faster, while or foreach?

Thank you, any suggestions are highly appreciated.

Hi,

 

I have made a database linked with php that I use a html form for.

The HTML form requests a particular date to retrieve, and the php form it is linked to then retrieves data from the MySQL database from that date.

 

My question is: I want there to be a restriction so that the retrieval can only be for dates before the present date (and certainly not any date in the future).

 

e.g. if it is 6th July 2020, then the database can only retrieve from the 5th July 2020 and before. (7th July 2020 onwards also is not allowed.)

Is there a way I can do it? Anyone who can guide me to a particular code function or something of that sort - I would be deeply grateful as my searches have not come up fruitful.

I have the following query:
 $getVideos = mysql_query("SELECT catergory, COUNT(catergory) as 'catCount' FROM videos GROUP BY catergory"); 

Using this in PHPMyAdmin returns the correct results of:
catergory | catCount
   0 

  |    7
   1 

  |    1
   10     |    2

How would get those results into a PHP array or what not...I have done this before but along time ago and cannot for the life of me remember how to do it.

Hopefully someone can point me in the right direction?

When I use PHP to gain data from another webpage I usually use
file_get_contents

Is there a faster way to retrieve data from webpages faster since it only seems to do around 200 website line retrievals per minute?

Is cURL faster?
Thank you

Here's the site: http://www.secretauctions.com/thank_atv_cb754.php#  (If anyone wants to see how the problem is occurring.  The Username and Password shown on the page are functional.)

Here's the problem: Whenever anyone tries to click to the second page of results, the Session fails.  Here's a short version of the code:

Code: [Select]
<?php
$username = "user493d";
$password = "w7atv"; 

session_start();  
$my_array=array($username, $password);
$_SESSION['login']=$my_array;

if ($_SESSION['login'][0]=="user493d" && $_SESSION['login'][1]=="w7atv")
include("atv_list.php"); 
else
include("sorry1.php"); 
?>
This works GREAT on the initial log-in.  But the moment anyone tries to go to the second page of results, the Error state trips, and they get the "sorry" page.  This isn't supposed to happen.  This is my first foray into Sessions, so I'm certain there's something I'm not understanding, but shouldn't the above code store the username/password, then use it to verify page reloads?  Can anyone tell me why it's allowing the Fail state to trip, when the initial test succeeds?  Or am I doing the whole thing wrong?

Hi guys,

I have a file location stored in mysql. when i populate the table i need this file location to be a hyperlink to the file itself, so the visitors can click like a normal link and open the file in word and pdf (both formats stored).

example of file location as in db "_private/Incident_Reports/Incident%20-%20Applecross%20-%2017%20December%202010%20-%20Website.doc"
example of php code Code: [Select]
echo $row['word_document'];
any ideas would be really appreciated.

Hello,

I have a webpage that runs some php code to control electrical devices. One part of it controls outside lights. Another part controls an electric door striker. I keep expanding the functionality of it and need to change one pin of the port without affecting the others. So far I use a different port for each function but I am out of ports so I need to use the different pins of the parallel port.

I am using a linux ubuntu server.
From my php webpage I issue this command: <?php exec("/home/setSerialSignal /dev/ttyS0 0 0"); ?> which controls the lights using the serial port. I can control 2 pins but I can't check the status of them so if I make a change to one pin it cancels the other.

For another one I use the parallel port with this command: <?php exec("/home/parashell 0x378 1"); ?> which turns on pin #2 of the parallel port.

Parashell has an executable called "pin". If you type the command "pin 0x378" it will return a value for the status of the parallel port. "1" for example which tells me that pin #2 is on. Is there a way to pass this value to a php variable?

I am looking to be able to read the status of the port and make changes to just the pin I want.

Lets say pin #2 is on and I want to turn pin #3 on. I would have to issue <?php exec("/home/parashell 0x378 2"); ?> to turn pin #3 on, but that would turn off pin #2. If I could pass the "1" from the "pin" command I could add it to the "2" and give it the command with a variable as "3".

Thanks in advance for any help you can give. I hope I explained it ok and didn't confuse everyone.


 


 

Problem:

I'm trying to make it so the array responds to the integer of status in the database. So, to check if it's one, I try this:


$get["status"]["1"] = "Message here...";


But, on my result, I'm just getting WWTT - And the value in the database for the ticket is 0. I'm not sure if I'm using the array correctly.

My full code:


<?php
session_start();
include("../includes/mysql.php");
include("../includes/config.php");
