PHP - Dynamically Changing Image

Hi,

This line of code works just fine for me:
$sql_quest = 'SELECT id, username FROM user ORDER BY id ASC LIMIT 0, 30';

I want to be able to set the integer values dynamically and I thought something like this would work:
$sql_quest = 'SELECT id, username FROM user ORDER BY id ASC LIMIT' . $my_int_value . ',' . $my_int_value + 30;

But it doesn't... Any ideas?

I've searched around the internet and can't find a good method to do this.

To start, I have a database with a field called 'fpath' that stores the filepath (root-relative) to uploaded PDF's. In this case, they're scanned personnel files. What I'd like to do is be able to download relevant PDF's based on a generated report... such as all PDF's of a certain category or all PDF's for a certain user.

If there's a specific PEAR package or other script out there that you know works well, I can research it on my own.. but each search result is bringing up a different method to do it, which makes me nervous.

Thanks!

This code works: 

// create object
$zip = new ZipArchive();

// open archive 
if ($zip->open('./download/zipfile.zip', ZIPARCHIVE::CREATE) !== TRUE) {
    die ("Could not open archive");
}


but, I want to create the name of the zip file dynamically.  The following code does not work ... doesn't give me an error, just doesn't create the zip file:

// create object
$zip = new ZipArchive();
$thisTime = time();

// open archive 
$thisZip = './download/'.$thisTime.'_download.zip';
$thisZip_b = $thisTime.'_download.zip';
if ($zip->open($thisZip, ZIPARCHIVE::CREATE) !== TRUE) {
    die ("Could not open archive");
} 



thanks in advance oh wise ones.

So i have an url routing class set up. I wan to call method via url so it would look something like this: http://www.mysite.com/index.php/Class/Method/Parameter. I was able to instantiate class like this:

Code: [Select]
$controller = new $this->UrlPath[0];

But i can't call method the same way
Code: [Select]
$controller->$this->UrlPath[1]();
Is there a way to call method with an array?

I have a slideshow that I am having to modify for my needs. The data file uses an array and i need this to be dynamic. I need to loop through all images in a directory and create the array. I have the directory being stored in a variable already. Now i just need to loop though all images in that directory to create the array like you see in the below code. You can also see the directory variable at the top. Can someone give me a hand with this please?

Code: [Select]

We recently migrated over to a new AMP platform that I built from source and now we can't dynamically generate images.  It seems like GD is properly included into PHP (although I didn't know then I could do it using dynamic modules):

My PHP configure is as follows:

==================================================
'./configure' '--prefix=/export/appl/pkgs/php/v5.3.9' '--with-apxs2=/export/appl/pkgs/httpd/latest/bin/apxs' '--with-mysql=/export/appl/pkgs/mysql/latest' '--with-mysqli=/export/appl/pkgs/mysql/latest/bin/mysql_config' '--with-gd=/export/appl/pkgs/libgd/latest' '--with-pear' '--with-png-dir=/export/appl/pkgs/libpng/latest' '--with-jpeg-dir=/export/appl/pkgs/jpeg/latest' '--with-curl=/export/appl/pkgs/curl/latest' '--with-freetype-dir=/export/appl/pkgs/freetype/latest' '--with-mhash=/export/appl/pkgs/mhash/latest' '--with-mcrypt=/export/appl/pkgs/libmcrypt/latest' '--enable-pcntl' '--enable-soap' '--enable-mbstring' '--with-zlib-dir=/export/appl/zlib/v1.2.5' '--with-ldap'
==================================================

The GD section in phpinfo is as follows:

I get broken image icons in IE and Chrome, and I get an "image cannot be displayed" msg in FF.

I'd appreciate someone clubbing me with a cluestick.

Hello -

I'm (very) new to php and working on a project and wondering if anyone can point the direction? (Not necessarily give the answer, but any helpful direction).

I need to take YouTube video id's, (built into an array), and post the various video clips.   Also the <object> code is in an php array.

(Code Below.. hard to explain).

Do I need to convert the array text into a string (as shown), and how do I take that string text and paste it into multiple youtube object posts? Note that the original $embedCode is commented out, '//), so that it can be referenced.

Any advice is appreciated!

<?php

$number = 0;
$youtubeIds = array("MX0D4oZwCsA","2v-v3jh-Cco","WuYDSa4BRaw","zwo48StJSr4","exOxUAntx8I");
//   $embedCode = '<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/__YOUTUBE_ID__?fs=1&amp;hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/__YOUTUBE_ID__?fs=1&amp;hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>';
$string = implode($youtubeIds);
$embedCode = '<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/'<?php $string?>'?fs=1&amp;hl=en_US"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/'<?php $string?>'?fs=1&amp;hl=en_US" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>';

I am trying to make an edit page to edit any of my post...so i designed a manage post page manage-posts.php with the given code:

Code: [Select]
    <?php 
echo '<form name="frmMain" action="del1.php" method="post" OnSubmit="return onDelete();">';
$objConnect = mysql_connect("hostname","username","password") or die(mysql_error());  
    $objDB = mysql_select_db("dbname");
    $strSQL = "SELECT * FROM text";  
    $objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");  
     
echo '<table width="600" border="1">';  
    echo '<tr>';  
   echo '<th width="91"> <div align="center">ID</div></th>'; 
echo '<th width="91"> <div align="center">Date</div></th>';  
    echo '<th width="91"> <div align="center">Title</div></th>';
echo '<th width="91"> <div align="center">Author</div></th>';
    echo '<th width="30"> <div align="center">Edit</div></th>';
echo '<th width="30"> <div align="center">Select</div></th>';
    echo '</tr>'; 
    while($objResult = mysql_fetch_array($objQuery))  
     {  
       ?>
    <tr> 
    <td><?=$objResult["id"];?></td>
    <td><?=$objResult["date"];?></td> 
    <td><?=$objResult["title"];?></td> 
    <td><div align="center"><?=$objResult["author"];?></div></td> 
<td align="center"><a href="edit.php?NewsID=<?php echo $objResult["id"];?>" name="edit">Edit</a></td>   
    <td align="center"><input type="checkbox" name="chkDel[]" value="<?=$objResult["id"];?>"></td> 
    <input type="hidden" name="id" value="<?=$objResult["id"];?>" />
    </tr> 
     <?
      } 
   
    echo '</table>';
echo '<input type="submit" name="btnDelete" value="Delete">'; 
    echo '</form>';

and i designed another page edit.php to perform deletion of that particular post with the following code "
Code: [Select]
<?php 
 
$objConnect = mysql_connect("hostname","username","pass") or die(mysql_error());  
    $objDB = mysql_select_db("dbname");
  
   $strSQL = "SELECT * FROM text";  
    $objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]");  
$objResult = mysql_fetch_array($objQuery);
?>
  <input type="hidden" name="id" value="<?=$objResult["id"];?>" />
  Title : <br /><input type="text" name="title" size="100"  maxlength="100" value="<?=$objResult["title"];?>"/> <br />
            Date : <br /><input type="text" name="date" size="20"  maxlength="12" id="TextBox" value="<?=$objResult["date"];?>"/> <br />
            Author : <br /><input type="text" name="author" size="20"  maxlength="100" value="<?=$objResult["author"];?>"/> <br />
            <br />
<input type="submit" value="Submit" name="submit" />
            </p>

</form></fieldset></div>

Hey Guys,

I'm querying a database that is going to return a html page. In this page I'm going to define content areas with a class.

eg:
<div class="category"></div>

Anywhere I have this class in the html code, I want to dynamically insert a link into it. So when I retrieve the code from the database, I need the code to check for this tag (class="category") and add a standard link (<a href="..">Add new Category</a>) 

Not 100% sure whats the most efficient way to go about this.

Hi there, so recently I have been trying to dynamically set the title on a page with PHP

note that the username variable is being passed thru a file that is required. Any help is appreciated

I am trying to set the HTML Page Title dynamically, but this code from my book doesn't work...

<title>
<?php
// Dynamically set Page Title.
if (isset($page_title)){
echo $page_title;
} else {
// Default Page Title.
echo 'Knowledge is Power: And It Pays To Know';
}
?>
</title>


What is wrong with it?

(All I see is the code in the Webpage/Window Title...)

I'm looking for any guidance on how to dynamically create css files. I want users to be able to select colors for fonts/backgrounds, borders, etc. from a form which they will submit and it will create a css file and put it in a certain folder. Can someone point me in the right direction?

Hello   I am using fpdf to generate pdf files based on certain csv files. Now the client wants certain fields of the generated pdf file to be 'interactive' . Is this possible ? Googling about editable (interactive pdf's) only confused me . any help ?    btw by interactive I mean fields that can be typed into directly by the client and then saved into the pdf .

Hi PhpFreaks,

I have a method that I need to be initialised  dynamically and I am not sure if the code below will work I have been able to workout if the method exists
but I have not found a way to it get to return the array. Has anyone go any ideas?

The error I get is: Catchable fatal error: Object of class Forms could not be converted to string
Code: [Select]
public function setMethodForms($methodName){
echo $methodName." and does it exist ". (int)method_exists($this->formsObj, $methodName);

//test to see if the method exists
if ((int)method_exists($this->formsObj, $methodName) == 1){
//if it does execute
//print_r ($this->formsObj->projects()); //test to see if object works
$return call_user_func($this->formsObj."->".$methodName."()");
}
return $return;
}

What I want to do is create a table out of records from a table that shows an image and a radio button under the image (so I would imagine it would be in 2 rows). I want it to have 3 columns across. Here's what I have to get and output the results:
    $fabricsql = "SELECT * FROM Fabric f, Images i WHERE f.SKU = i.SKU";
        //echo $fabricsql;
        $fabricResult = mysql_query($fabricsql);
        $i=0;
        while($fabricAssoc = mysql_fetch_assoc($fabricResult)){
            //echo $fabricAssoc['SKU']. "+ ".$fabricAssoc['Name'];
            echo "<a href=\"\"><img src='../../".$fabricAssoc['ThumbPath']."' alt='".$fabricAssoc['Description']."' width='".$fabricAssoc['ThumbWidth']."' /></a><br />
             <input type=\"radio\" name=\"fabricSelect\" value='".$fabricAssoc['SKU']."' id=\"RadioGroup1_".$i."\" /><br /><br />";    
             $i++;
        }
        

Any help is much appreciated. I'm not even sure this is the best way to go about this so any suggestions are appreciated.
