PHP - Trouble Appending File

Hi everyone! Nice to meet/see/read you.

This is my first post and it will probably be a lame one so apologies. I'm a pretty good frontend designer and I've always struggled to learn PHP and my new job is forcing it on me so I'm happy in a "throw me in the deep end" kinda way.

I am really stuck! I have a single page that is using jquery to scroll my content left and right via the menu (example attached). What I am trying to do is when on the homepage, don't show the "main logo". When on any other link, show it.

I immediately thought of an if/else statement but realised I don't know what or how exactly to target since everything is on the same page and the URL doesn't change. Could I target the image title that is the only image on the homepage? So, something like:

<?PHP
$image_title = 'home';

if (XXXXX($image_title)) {
echo "IMAGE";
} else {
echo "NO IMAGE";
}

?>
I know that's wrong, I put XXX where I feel like something possibly helpful should go. Heh.   

I'm not asking for someone to write code for me, I'm happy to learn but but I would be very grateful if someone could just guide me to what I need to do and off to Google I will go. I haven't been able to find anything that is like: "if image title equals".

Hmm... I hope I can do this with PHP.

Thanks again,
Linda

Trying to a. check if dir exists if not create it, and b. save an uploaded file to that directory.  Nothing however is working but I'm pulling no errors, heres the code:



$test_pic = $_POST['test_pic'];
// I've also tried       $test_pic = $_FILES["test_pic"];     : with no success
if (is_uploaded_file($test_pic)) {
if (!file_exists("tests/uploads/" . $test_name . "/")) {
$create_test_folder = (mkdir("tests/uploads/" . $test_name));
if (!$create_test_folder) {
echo "cant create folder";
die;
}
}
$target_path = ("tests/uploads/" . $test_name . "/" . $test_name . "_1");
if (($_FILES["test_pic"]["type"] == "image/gif")
   || ($_FILES["test_pic"]["type"] == "image/jpeg")
 || ($_FILES["test_pic"]["type"] == "image/jpg")
 || ($_FILES["test_pic"]["type"] == "image/png")
 && ($_FILES["test_pic"]["size"] < 50000)) {
if (!copy($test_pic, $target_path)) {
echo "cant copy picture";
die;
}
} else {
echo "file type or size bad";
die;
}
}


and I understand its not at all public-safe but I'm just wanting to get it to work before I throw in the security.  Thanks for the help!

Hey guys,

I have a script that grabs data from a separate .txt file which is used to perform certain actions within a user's account. The data I'm having trouble with is user key which is used to authenticate an http header. An example of what the txt file would hold is this:

360235276 PbI1c5+PGHSshccYd58AklmTgf5u+tbWZplMRYYxFSivRYw4AZhaVNHwADozYZhZhPnXRSV1rmsrhf1td7w6bJbySZmPHLl+hleyz/Ht4iM=
477947328 cXTnFEVP74RWtAgqM5BlwtgW2i9rP/v44oANzwF+yJZ+9mpvaschyo/HaYP1qUXgIK8nK7jy74iSCEHAgpPgPdryzpReM5cbnVDjRw7h9S0=

The format I have is: account_ID user_key
New account on a fresh line. So in my script I have it grabbing the data as so:


$User_DataFile = "accountdata.txt";

$AccData = file($User_DataFile, FILE_SKIP_EMPTY_LINES);


foreach($AccData as $line_num => $line)
{
$AccData = explode(" ", htmlspecialchars(str_replace("    "," ",$line)));

if(stristr($AccData[1], "\n")) $AccData[1] = substr($AccData[1], 0, strlen($AccData[1])-2);

$AccountID = $AccData[0];
$UserKey = $AccData[1];
echo "Account ID: ".$AccountID."<br/>User Key: ".$UserKey."<br/><br/>";


I have it set to simply echo out the data for debugging which is where I noticed that any slashes or plus or equal signs were not included.
When run in Apache it returns this:

Account ID: 360235276
User Key: PbI1c5+PGHSshccYd58AklmTgf5u+tbWZplMRYYxFSivRYw4AZhaVNHwADozYZhZhPnXRSV1rmsrhf1td7w6bJbySZmPHLl+hleyz/Ht4iM

Account ID: 477947328
User Key: cXTnFEVP74RWtAgqM5BlwtgW2i9rP/v44oANzwF+yJZ+9mpvaschyo/HaYP1qUXgIK8nK7jy74iSCEHAgpPgPdryzpReM5cbnVDjRw7h9S0

Account ID: 503724987
User Key: XXEJsklZTFaTx8MLjuNIz0S65Sn02rgbHl2sahdReQdadKP39 evIXUoYdr5NyQMWDVE7cRpvn+zJ7mteH7WJzVh0U/sOcSG7kfcuaWpAOfo

So as you can see by comparison there is no slashes or plus or equal signs present, which is going to be a major problem. Is there any way of getting around this problem?

Thanks.

Hello fellow developers,

Let me start by saying I'm still a PHP noob so please don't go too hard on me if I my code reflects this noobishness...

So I'm trying to build a (very) simple RSS reader using jQuery and PHP. When the user clicks on an option from a dropdown, an AJAX call is made and passes the url selected from the list to a PHP script.

The PHP script then loads the appropriate xml file from an 'xmlcache' folder. Everything is working just fine for files named as such:

somefilename_1231231231.xml

The problem is that I need it to be able to load files which have been urlencoded such as:

http%3A%2F%2Ffeeds.feedburner.com%2Fajaxian_1235523548

In case you're wondering, the numbers at the end are a timestamp which will determine if the reader will load a cached copy of the desired xml file (if it's less than an hour old) or if it needs to get a fresh version (this part of the code is not written yet). Here is a look at my script thus far:

<?php

$url = "./xmlcache/" . urlencode($_REQUEST['url']); //access url from AJAX call
echo $url; //outputs -> "./xmlcache/http%3A%2F%2Ffeeds.feedburner.com%2Fajaxian_1235523548.xml", which is the same as the file's name
$curTime = time();
$urlParts = explode('_', $url);
$urlTime = intval($urlParts[1]);
$diff = $curTime - $urlTime;
$urlAge = 60 * 60; //60sec * 60min = 3600sec or 1 hour

if(file_exists($url)){
        if($diff > $urlAge){ //the > will be switched to < to make logical sense once testing is done.
                $xml = simplexml_load_file($url);
               
                //ROOT TAG
                foreach($xml as $key0 => $value){
                        echo "$key0: $value";
                        foreach($value->attributes() as $attributeskey0 => $attributesvalue1){
                        echo "$attributeskey0: $attributesvalue1";
                        }
                        echo "<br />";
                       
                        //1 LEVEL BELOW ROOT TAG
                        foreach($value as $key => $value2){
                                echo "$key: $value2";
                                foreach($value2->attributes() as $attributeskey => $attributesvalue2){
                                        echo "$attributeskey = $attributesvalue2";
                                }
                                echo '<br />';
                               
                                //2 LEVELS BELOW ROOT TAG
                                foreach($value2 as $key2 => $value3){
                                        echo "$key2: $value3";
                                        foreach($value3->attributes() as $attributeskey2 => $attributesvalue3){
                                                echo "$attributeskey2 = $attributesvalue3";
                                        }

                                        foreach($value3 as $key3 => $value4){
                                                echo "$key3: $value4";
                                                foreach($value4->attributes() as $attributeskey3 => $attributesvalue4){
                                                echo "$attributeskey3 = $attributesvalue4";
                                                }
                                                echo '<br />';
                                                //4 LEVELS BELOW ROOT TAG
                                                foreach($value4 as $key4 => $value5){

                                                        foreach($value5->attributes() as $attributeskey4 => $attributesvalue5){
                                                                echo "$attributeskey4 = $attributesvalue5";
                                                        }
                                                        echo '<br />';
                                                        //5 LEVELS BELOW ROOT TAG
                                                        foreach($value5 as $key5 => $value6){
                                                                echo "$key5: $value6";
                                                                foreach($value6->attributes() as $attributeskey5 => $attributesvalue6){
                                                                        echo "$attributeskey5 = $attributesvalue6";
                                                                }
                                                                echo '<br />';
                                                        }
                                                }
                                        }
                                }
                                echo '<br />';
                        }
                        echo '<br />';
                }

        }else{
                //need to create the XML file from scratch, do a curl function, or read from a text file
                echo "need a new version";
                //@unlink("$url);
        }
       
}else{
        echo "That file does not exist.<br/>";
}

?>

The error message I'm getting is this:


Warning: simplexml_load_file() [function.simplexml-load-file]: I/O warning : failed to load external entity "./xmlcache/http%3A%2F%2Ffeeds.feedburner.com%2Fajaxian_1235523548.xml" in C:\wamp\www\reader\loadfeed.php on line 13

Warning: Invalid argument supplied for foreach() in C:\wamp\www\reader\loadfeed.php on line 16


The second error is obviously thrown because the file doesn't get loaded.

I appreciate any help you gurus have to offer, and if you have any suggestions for the best way to load a fresh version that will be handled by the first else statement, I'm all ears.

Thanks guys!

I am very new to php and am trying to create a simple application that uploads a PDF file to a database. I have one field for the Volume Number and on file field for the PDF to be uploaded. My issue is i can't get the PDF to upload or insert the name of the pdf (eg volume1.pdf) into the data base.

I would also like to point out that I know i have a low post count, but i only seek help when i truly need it and have exhausted all other resources...

Here is what i have, please go easy on me this is my first round at php:
Code: [Select]
<?php
if(isset($_POST['submit'])){
$vol_num = $_POST['vol_num'];
$pdf = $_FILES['pdf']['name'];
$path = '../pdf/'.$_FILES['pdf']['name'];
move_uploaded_file($_FILES["pdf"]["tmp_name"], $path);
        mysql_query("INSERT INTO volumes set vol_num='$vol_num', vol_link='$pdf'") or die (mysql_error());
echo "<script>location.href='add_volume.php'</script>";
}
?>
what am i doing wrong here?

Thanks in advance

Hi.  So I've coded many a file upload form and never had any trouble.  Until now.  For some reason when I try to upload MP3 files, I'll hit submit and the page just reloads.  Once it does so, the file upload field is once again blank.  What's odd is that images and documents upload just fine.  It's only audio tracks that cause the page to reload and clear.  My php.ini max file upload size is at this point set to 100M, and the files I'm trying to upload are under 10M.  Any ideas?  Here's the form code, just to post it-- pretty basic.  I'm at a loss here....  Any ideas would be appreciated.  Thanks very much.



<form action="test.php" enctype="multipart/form-data" method="POST"/>


   <input type = "file" name = "audio" />
   
   <p><input type ="submit" name="submit" value="do it."/><p>

</form>

I am trying to append data to a variable through each loop of a MySQL array, but I am doing it wrong. Is this possible? Here is the code.

This code is for creating a PDF  with fpdf and a third party table class. Its only displaying the last table data in the loop when I echo $html so the data is being overwritten each loop.

Hi!  Thank you in advance for the time and assistance.

I am writing a form and some php code that writes to a text file.  I have that accomplished.    My issue is that my form that writes to the text file appends to the bottom of the text file and I need it reversed.  The latest form entry needs to be on top... and then the older posts to follow. I have tried the w+ r+ and c+ but that is not doing it.  Is there something that I am missing?

I appreciate the assistance!

Hi Guys

Again, another noob question that I can't seem to find a concise answer to.

What is the best way to append a query string to a url?

I've tried using the Header() function but this didn't seem to work - i.e.

Code: [Select]
Header("Location: enc.php?ID=test");
My goal is to change the query string depending on the output of various if else statements. For instance if $test isset then execute some code.

The script will be self contained so it'll be posting back to itself with the query string and reacting differently depending on the query string.

Any ideas?

PS sorry if i am asking too many questions. Eager to learn and struggling to find answers to some things.

What I basically want to do (and not sure if this is possible) is to append a different query string based on

Hey guys

This is the first loop i have attempted on my own, so please tell me if ive done something completely stupid..

What happens is the suer specifies a number of thumbnails on the previous page, these are posted to the form and then that amount of thumbnails should be displayed.

Heres what i have so far
$cd = 0;
while ($cd < $numberofthumbnails) {
$displaythumbs . '<div class="ThumbnailHolder">
     <div class="LeftThumb"><a class="group" href="../../../Images/Lighthouses/Beachy-Head/1.png"><img src="../../../Images/Lighthouses/Beachy-Head/Mini/Thumbnail-1.png" width="430" height="200" alt="Thumbnail 1"></a></div>
     <div class="RightThumb"><a class="group" href="../../../Images/Lighthouses/Beachy-Head/2.png"><img src="../../../Images/Lighthouses/Beachy-Head/Mini/Thumbnail-2.png" width="430" height="200" alt="Thumbnail 2"></a></div></div>
';
$cd++;
}

Essentially what im trying to do is as thumbnail code to $displaythumbs for each time the loop goes round. What am i doing wrong?

Thanks

Danny.

Hi all

I am trying to loop through an array and output as JSON.
What I'm looking to do is create something like:

Code: [Select]
  "something": [
{"title":"Test 1"},
{"title":"Test 2"}
],

Notice that the final row has no comma.

My code is as follows:


<?php foreach($something as $thing): ?>
<?php $something_array = array('title'=>$thingt->getId()); ?>
<?php echo json_encode($something_array).','."\n"; ?>
<?php endforeach; ?>


I had to add a comma to the end of the array, or the JSON rows would not be ended with one.

How can I get it so that, no matter how many items are in the array, the last row, wil not have the comma at the end?

With the comma at the end, my JSON doesn't validate

Thanks

I have an array of $fl
By using values of this array, i want to create a new string.
I need string size will be maximum 200 characters.
When i try below code snipped, $f value is added to string two times.
How can i add $f to array only one time, with checking size of string.
Thank you

Code: [Select]
$fl=getsomelist(); // gives an array
$userList='';
foreach ($fl as $f) {
    if ( strlen($userList .= $f) <= (200) ) {
        $userList .= $f;
    } else {
        break;
    }
}

Hello.

I'm trying to append the loop keys and values into a string and store it into a hidden field.

This is the code I have :

Code: [Select]
if (isset($_POST['ordered'])) {
// We can assign $_POST['product'] to a variable to make it easier to type out
$prod = $_POST['product'];
// Throw a little intro to see how many they checked
echo 'You selected ' , count($_POST['ordered']) , ' products.';
// Now we loop through it and get the IDS that were selected
// Foreach lets you select the $key and the $value for each iteration of the loop //

$strOrder = "";

foreach ($_POST['ordered'] as $key=>$id) {
echo '<p/>
ProdName: ' , $prod[$id]['name'] , '<br/>
ProdPrice: ' , $prod[$id]['price'] , '<br/>
ProdQty: ' , $prod[$id]['qty'] , '
<hr/>';

$strOrder .= $key . " " . $id;

$TOT += $prod[$id]['price'] * $prod[$id]['qty'];

}

$TOT2 = $TOT + 55;

echo '<input type="hidden" Name="TOT" value ="'. $TOT .'">';
echo '<input type="hidden" name="TOT2" value =". $TOT2 .'">';

echo '<input type="hidden" name="Order" value=". $strOrder . '">';
}
strOrder does not get set to a value.

Hi,   what I'm tryng is to append a table row with associated jquery code...   I have a jquery code just like this

<script type="text/javascript">
jQuery(function($) {

  var rowCtr = 0;
  $('.addRow').click(function(){
		$('#tableID > tbody:last').append('<tr name="rowEq['+rowCtr+']" id="rowEq['+rowCtr+']"><td>'+
				'<select id="stype'+rowCtr+'" name="rowData['+rowCtr+'][equipment_type]">'+
					'<option value="0"> -- </option>'+
					'<option value="1"> Type 1 </option>'+
					'<option value="2"> Type 2 </option>'+
					'<option value="3"> Other </option>'+
				'</select>'+
				'<input id="other_type'+rowCtr+'" type="text" name="rowData['+rowCtr+'][other_type]">'+
				);
				
				$('#stype'+rowCtr).change(function() {
			
				if(jQuery('#stype'+rowCtr).val() == '3')
				{
					jQuery('#other_type'+rowCtr).show();
				}else{
					jQuery('#other_type'+rowCtr).hide();
				}
				});
				
				if(jQuery( '#stype'+rowCtr ).val() != '3')
				{
					jQuery('#other_type'+rowCtr).hide();
				}
				rowCtr++;
   });

});

				

</script>

And html like this..

<input type='button' class='addRow' value="Add Row">
<form>
    <table id="tableId">
       <thead>
           <tr>
               <th> Type </th>
           </tr>
       </thead>
        <tbody>
            <tr>
                <td>
                  dummy text..  
                </td>
            </tr>
        </tbody>
    </table>
</form>

The appending is ok but the hidding/showing of "other_type" field is not working. It always hide "other_type" field even if I already selected the 'other' option.    tbl1.png   3.38KB   0 downloads
