PHP - Using The Good Old In_array() Function. But...

Im getting a warning with in_array.I have used if() inside for loop to check if value has already been printed or not. If not it will print and save the value in $done[].Can someone please point me out my mistake that i am getting a warning.

Code: [Select]
<?php
             for($i=0;$i<=$count;$i++)
                {   
                    $count_final = explode("_", $result[$i]);
                   if (in_array($count_final[0],$done)) 
                    {  //Line 480
                    echo "<tr>";
                    echo"<td>$count_final[0]</td>";
                    $templ = $count_final[0]."_left";
                    $tempr = $count_final[0]."_right";
                    $cleft = $count_middle[$templ];
                    $cright = $count_middle[$tempr];
                    echo"<td>$cright</td>";  
                    echo"<td>$cleft</td>";
                    echo "</tr>"; 
                    $done[] = $count_final[0];
                   }
                }    
?> Code: [Select]

Hello

I'm using tcpdf to convert some stuff to pdf.
On my local computer running wamp my script works perfect and the pdf is generated without problems
When i put my files in a webserver i got this error:
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/vieira/public_html/topdf/dbcon.class.php on line 68

Line 68 is:
if(in_array($key,$arr_switches)){   //check switches

My complete code is:

    // Get fields of enum on/off switches type
    $result2 = mysql_query("SHOW FIELDS FROM $db_name.$table");
    $counter=0;    
    while($row = @mysql_fetch_array($result2)){
        //echo $row['Field'] . ' ' . $row['Type']."<br/>";
        if($row['Type'] === "enum('on','off')"){
            $arr_switches[$counter] = $row['Field'];
            $counter++;
        }        
    }
    //print"<pre>"; print_r($arr_switches); print"</pre>";exit;
    
    $counter = 0;
    while($row = @mysql_fetch_array($result)){
        foreach( $row as $key => $val ){
            if(!is_numeric($key))
            {
                $row_rs_certidao[$key] = $val;
                if(in_array($key,$arr_switches)){   //check switches
                    $record_key[$counter] = htmlentities('<?php if (!(strcmp($row_rs_certidao['."'".$key."'".'],"on"))) {echo "x";} ?>');
                    if($val==='on') $record_val[$counter] = "x";    //turn on switches
                    else $record_val[$counter] = '';                //turn off
                }else{
                    $record_key[$counter] = htmlentities('<?php echo $row_rs_certidao['."'".$key."'".']; ?>');
                    $record_val[$counter] = htmlentities($val);
                }
                $counter++;                
            }            
        }        
    }

Anyone can help?

I have a long list of variables with form fields inserted into them like this:


$page_id = $_POST['exclude'];


I just turned on WP_Debug just to see which error messages would come up and to my surprise it wasn't that bad, the most error messages were "Call to Undefined function".

The solution to this problem is simple, all I  have to do is wrap an isset around all the form field variables, like this:


$page_id = isset($_POST['exclude']);


My question is, is this really necessary or considered as good practice? Should I now go ahead and wrap to all the variables in that long list an isset around?

Or should I just turn WP_Debug off again and leave it as is?

I personally would like to adopt to the good practice way, but I don't know how much of an advantage it is to wrap an isset around every single form field variable.

Any suggestions?

I'm reading over this book and I came across something that looked very odd:

public function DisplayHeader()
{
    ?>
    <table width="100%" cellpadding="12"
    cellspacing="0" border="0">
    <tr bgcolor ="black">
    <td align ="left"><img src = "logo.gif" /></td>
    <td>
    <h1>TLA Consulting Pty Ltd</h1>
    </td>
    <td align ="right"><img src = "logo.gif" /></td>
    </tr>
    </table>
    <?php
}

In the function it closes a php tag, uses raw html that is rendered as is on the page, and then returns back to opening the php tag. I understand why it is being done. It is easier to write raw html here than to echo it in a php block, but it just looks odd. Anyone actually use this technique?  

I can't access an array value in a multidimensional array.  The if should be echoing true.  $news['companyid'] is equal to 1, but I must not be using in_array correctly.

Code: [Select]
echo '<pre>';
print_r($own_company);

if (in_array($news['companyid'], $own_company))
{
echo "true";
}

Output
Array
(
    => Array
        (
            [companyid] => 1
            [companyname] => Oaysus
            [companytag] =>
            [companywebsite] => http://oaysus.com
            [country] => 1
            [state] => 0
            [city] =>
            [industry] => 4
            [stage] => 2
            [capitalrequested] =>
            [guestviews] => 0
            [iviews] => 3
            [eviews] => 3
        )
