PHP - If Statements, Buttons And Null

Hey Guys,

I am creating an array and I have a need to put a if statement inside it. Is this even possible?

Here is where I am at so far, its just not working.


 function load_permissions($gid)
    {
     $data = array();
     $this->db->select('`groups`.`name` AS `permission_name`, `permissions`.``');
$query = $this->db->get('`groups`,`permissions`');
if ($query->num_rows() > 0){
foreach ($query->result_array() as $row){
  $data[] = array(
  "name" => $row['permission_name'],
  "read" => if($row['level'] >= 1)
   { 
    img("img/true.gif")
   } else { 
    img("img/false.gif")
   },
 
  );
  }
 }
 
 $query->free_result();
return $data;



Thanks,
Peter

The below is constantly loading the password page no matter what is enter in the password input on the form (on another page). I have checked the $login variable by echoing it and it is carrying the value from the field.


<?php
$off="yes";
$login=$_POST['login'];
if($off=="yes" && (!isset($_SESSION['login']) || $_SESSION['login']!="pass")){
    if($login=="" || $_SESSION['login']!="pass"){
    header('Location: ./index2.html');
    exit();
    }
    elseif(!isset($_SESSION['login'])){
    session_start();
    $_SESSION['login']=$login;
    header('Location: ./index.php');
    exit();
    }
}
elseif($off=="no" || $_SESSION['login']=="pass"){
content goes here.
}
?> 

How to write 2 "if" statements together?

if($userResult==$myResult) and ($userResult<0)
{

Hey guys,

is there any way to have a LIKE condition on an IF statement?
Something like:
Code: [Select]
if $GET_['WTV'] LIKE %LOVE% {
$category=romance
Any clues?
Thanks in advance.

Anything wrong with this because I got a parse error ONLY after adding to create this.

<?php
                            $visible = array('Yes', 'No');
                            foreach($visible as $visible):
                            $visible2 = array('yes', 'no');
                            foreach($visible2 as $visible2):
                        ?>      

Hello, I am learning PDO SQL statements, I have mananged to connect using PDO:


Code: [Select]
try
{
$this->link = $dbh = new PDO('mysql:host='.$this->dbhost.';dbname='.$this->dbname.'', $this->dbuser, $this->dbpass);
}
catch (PDOException $e)
{
echo 'Connection failed: ' . $e->getMessage();
}


I am not getting any error, so I guess that is a good start. I then tried the PDO SQL statement out. My old mySQL query is commented out in the


Code: [Select]
if (isset($_SESSION['id']) && isset($_SESSION['password']))
{
$_SESSION['id'] = ( isset( $_SESSION['id'] ) ) ? $_SESSION['id'] : FALSE;
$_SESSION['password'] = ( isset( $_SESSION['password'] ) ) ? $_SESSION['password'] : FALSE;


//$logged = mysql_query("SELECT * FROM `db_members` WHERE `id`='".$_SESSION['id']."' AND `password` = '".$_SESSION['password']."'");
//$logged = mysql_fetch_array( $logged );

// the new pdo statement
$ff = $dbh->prepare('SELECT * FROM db_members WHERE id = '.$_SESSION['id'].' AND password = '.$_SESSION['password'].'');

$ff->execute();
$logged = $ff->fetchAll();

echo $logged['username'];
}

I am trying to assign the session to logged variable. So all I am asking is go into db_members and check the id and password that is the same as session id and password and collect the rows data such as username.

My login script and everything works perfectly, even session id and password is valid when echo'd but I cannot assign it to the logged variable like my old sql statements.


Code: [Select]
$logged = mysql_query("SELECT * FROM `db_members` WHERE `id`='".$_SESSION['id']."' AND `password` = '".$_SESSION['password']."'");
$logged = mysql_fetch_array( $logged );

I used other PDO statements and it works perfectly but I just don't understand why this is not working.... can I please get some help if you have any solution to this?

I am trying to write an if statement that checks to make sure the information put in the text box is an imbedded file. Does anyone know how to do that?

I have a general dbInsert class method that accepts three arguments: table, fields, and values - the last two each as an array. I am using a PDO connection and prepared statements to sanitize everything. I am having a problem with the bindParam() function accepting the parameter ID's though... here's my code and the result I am getting, any advice?

My arguments:


$this->_table   =  "testdata";
$this->_fields  =  array('product_id', 'store_id', 'description', 'price', 'colors', 'sizes');
$this->_values  =  array("20002157", "2005", "Kids polo shirt", "12.59", "White", "Large");


My object:


$_crud = new Crud();
$_makeCrud = $_crud->dbInsert($this->_table, $this->_fields, $this->_values);


My class:


public function dbInsert($table, $fields, $values) {

      $_table = $table;
      $_fields = implode(", ", $fields);

      // Create and format the list of insert values
      $_values = "";  

      // replaces values with "?" placeholders
      foreach ($values as $value) {
            $_values .= "?" . ", ";
      }

      // trims off last comma and space
      $_values = substr($_values, 0, -2);

      // checks database connection
      if (isset($this->_dbh)) {

            // Create the SQL Query  
    $this->_sql = 'INSERT INTO ' . $_table . ' (' . $_fields . ') VALUES (' . $_values . ')';

            // Build the query transaction
            $this->_dbh->beginTransaction();

            // Build the prepared statement
            $this->_stmt = $this->_dbh->prepare($this->_sql);

            // Bind the parameters to their properties
            foreach ($values as $key => $val) {
                  
                  // starts $key at 1
                  $key = (int) $key + 1;
                  $this->_stmt->bindParam($key, $val);
               }

            // Execute the query
            $this->_stmt->execute();

            $this->_affectedRows = $this->_stmt->rowCount();

      }
}


What my new table row should look like:

Code: [Select]

product_id     store_id      description                        price       colors      sizes
----------------------------------------------------------------------------------------------
20002157       2005          kids polo shirt                    12.59        white      large



But this is what my new row DOES look like:

Code: [Select]

product_id     store_id      description                        price       colors      sizes
----------------------------------------------------------------------------------------------
Large              0         Large                               0.00        Large      Large



So it's taking the value of that last $value and inserting it in all the fields, the store_id and price are 0 and 0.00 because of their numeric type...

I assume it is a syntax error, missing quotes somewhere, but where?

Hey everyone, i am currently working on a "contact us" script. I want the form to first allow the user which department they want to email. E.g. "Sales" and "Support" By changing this drop down box it will change which email the form is sent to. Im having trouble setting the PHP side of this script up to change the emails. Any help regarding this matter is much appreciated.

I always have trouble reading shorthand statements, as i am used to always using brackets. So when i view someones code and they use shorthand, i get confused.  Can i get a clear explanation on the example below:

if ( have_posts() ) : while ( have_posts() ) : the_post();
					the_content();
					
					endwhile; else: 
					
						echo "<p>Sorry, no posts matched your criteria.</p>";
					
					endif;

I've always been accustomed to using brackets, so i have trouble understanding the above quickly.

I need to insert a large variable number of records into a mysql table.
I can do this using a while loop and insert queries in the loop but its slow and ive been given to understand its a bad idea.
I have heard that I can insert multiple rows with one query, but how to construct the query?

This code can perfectly and reliably display a statement with echo:
Code: [Select]
<?php
$querytestquery='"INSERT INTO test(qval1, qval2) VALUES';
echo $querytestquery;
$querymax=10;
$querystart=0;
while ($querystart<$querymax) {
$qval1=1*$querystart;
$qval2=2*$querystart;
$queryadd="($qval1, $qval2)";
echo $queryadd;
if ($querystart<$querymax-1) {
echo ',';
}
$querystart++;
}
echo '"';
?>

"INSERT INTO test(qval1, qval2) VALUES(0, 0),(1, 2),(2, 4),(3, 6),(4, ,(5, 10),(6, 12),(7, 14),(8, 16),(9, 18)"

But I don't understand how to set a variable equal to the displayed query so that I can have php construct the statement based on the values and the number of records I want to update or insert.

How could I make it so that if the $date variable is past than $memberdate then something shows else something else does.


<?php
$date = date('Y-m-d H:i:s', time()-3600);
$memberdate = '2011-01-29 01:03:28';
?>

Thanks in advance, I realised I could convert it into a unix timestamp but there must be a better way. Ty.

Hello:

I am writing this code:
Code: [Select]
<?php

include('include/myConn.php');
include('include/myCodeLib.php');

$zip_id = $_REQUEST['zip_id'];

$query=mysql_query("SELECT zip_id,city,full_state,zip FROM zip_codes WHERE zip_id = $zip_id") or die("Could not get data from db: ".mysql_error());

while($result=mysql_fetch_array($query))
{
  $zip_id=$result['zip_id'];
  $city=$result['city'];
  $full_state=$result['full_state'];
  $zip=$result['zip'];
}

?>

<!DOCTYPE HTML>

<head>

<title></title>

</head>

<body>

<?php echo $city; ?>, <?php echo $full_state; ?> <?php echo $zip; ?>

</body>

</html>


It works fine as far as writing out the "City, State Zipcode", but I wanted to see if there is a way to "join" the 3 statements together so it can be written as just 1 statement. Like:
Code: [Select]
<?php echo $city, $full_state $zip; ?>

What is the trick to doing this?

Thanks in advance.

this is working fine :

Code: [Select]
while($tags=mysql_fetch_array($d_b->sql_answer,MYSQL_ASSOC)){
echo $tags['tag_name'] . "<br/>";
}
display :

Code: [Select]
html
css
javascript
c++
php
but when i try to do some sql statements inside like this :

Code: [Select]
while($tags=mysql_fetch_array($d_b->sql_answer,MYSQL_ASSOC)){
$sql="SELECT * FROM user
      WHERE user_languages LIKE '% {$tags[tag_name]} %'";

//to apply the $sql
$d_b->apply($sql);
//number of results
$num=$d_b->num_rows();
$sql="UPDATE tags
      SET tag_folowers={$num}";
$d_b->apply($sql);
}
it return an error : Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given

Okay i'm trying to compare these sets of variables.

code looks like this..

Code: [Select]
if(
               $row->cash > $finalcash &&
               $row->core1 > $finalcore1 &&
               $row->core2 > $finalcore2 &&
               $row->core3 > $finalcore3 &&
               $row->core4 > $finalcore4
               ) {
return true;
}
else {
return false;
}
First question is this the appropriate way of doing this?

Or would a nested if statement work better?

example:

Code: [Select]
if ($row->cash > $finalcash) {
    if ($row->core1 > $finalcore1) {
        if ($row->core2 > $finalcore2) {
            if ($row->core3 > $finalcore3) {
                if ($row->core4 > $finalcore4) {
                   
                } else {
                    return false;
                }
            } else {
                return false;
            }
        } else {
            return false;
        }
    } else {
        return false;
    }
} else {
    return false;
}
I know it looks pretty messy, so i'm wondering if anybody is aware of an alternative to achieving this?
