PHP - Handling Empty String Returned From Js To A Php Array
Hi all ! What would be the best way to identify and handle an empty array sent from JS to PHP? This rather simple looking problem has resulted in a lot of confusion to me. $_POST['myArray'] = ""; // an empty string -- this is how the empty array from JS is received in PHP
Similar TutorialsHi, I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads. Here is uploadify.php as it currently looks: Code: [Select] <?php session_name("MyLogin"); session_start(); $targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder; $targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name']; // Validate the file type $fileTypes = array('m4a','mp3','flac','ogg'); // File extensions $fileParts = pathinfo($_FILES['Filedata']['name']); if (in_array($fileParts['extension'],$fileTypes)) { move_uploaded_file($tempFile,$targetFile); echo '1'; } else { echo 'Invalid file type.'; } } echo $targetFolder; ?> I added Code: [Select] echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'. For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'. The folder for username exists, with correct permissions, and when I manually enter Code: [Select] $targetFolder = '/songs/nick';all works fine. Which strikes me as rather strange. I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string. Any help would be much appreciated. It's the last issue with a website that was due to go live 2 days ago! Thanks, Nick Is their a way to format lr.submit_time in every record that is returned in the $results array without doing like a for/foreach loop? Like array_walk() or something similar? $query = " SELECT lr.*, l.make, l.model, l.part_number, l.description, pd.job_number, pd.line_item, pd.enterprise, pd.description, pd.qty AS order_qty, log.name AS user_full_name FROM leds_requests lr LEFT JOIN leds l ON l.id = lr.product_id LEFT JOIN production_data pd ON pd.id = lr.order_id LEFT JOIN login log ON log.user_id = lr.user_id WHERE lr.id IN( SELECT MAX(id) FROM leds_requests WHERE status_id = 0 GROUP BY order_id, product_id ) AND lr.id NOT IN( SELECT id FROM leds_requests WHERE lr.id = id AND status_id IN(1, 2, 3, 4) ) GROUP BY order_id, product_id, job_number "; $statement = $pdo->prepare($query); $statement->execute(); $results = $statement->fetchAll(); echo json_encode($results);
I'm trying to develop some php that will execute a MySQL query and move the results into XML. In this particular instance, only one record is expected to be returned, and that one row will contain all the customer data, such as last name, first name, address1, etc. While I can get my code to work and create the xml if I hard-code in all the keys (MySQL column names), I would like it to dynamically step through all the keys/MySQL column names so that if the db changes later (add more columns, for instance) the code generating the XML won't need to be altered. It should take the MySQL column name, create an element based on the column name, then create a text node and insert the value. Currently I'm just at the spot of testing by echoing the appropriate key/value pairs. The code is stopping after the first key/value without going through the rest of the columns. What do I need to do in order to get it to dynamically step through each column and get the key/value? Here's the relevant code: if($_POST['buscode']) {echo "buscode is: ".$_POST['buscode']."<HR>";} else {echo "ERROR WITH RETRIEVING BUSCODE<HR>";} $buscode = $_POST['buscode']; $query = "SELECT * " ."FROM customers " ."WHERE buscode = '$buscode'"; echo "Query will be: ".$query."<HR>"; $result = mysql_query($query); if($result){echo "Success retrieving data from ats_ajax.<HR>";} else{echo "Error retrieving data from ats_ajax\; MySQL error is:".mysql_error($result)."<HR>";} //////////////////////////////////////// // Let's test getting the keys and values from the array.... /////////////////////////////////////// while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { echo "This is step ".$i."<BR>"; $key = key($row); echo "Key is: ".$key."<BR>"; echo "Value is: ".$row[$key]."<BR>"; $i++; }//close of while If the value of $keyword is empty, only then it should print "Hi". else if should print "Hello". Problem is sometimes the value $keyword will be "0". How to handle this condition Code: [Select] $keyword=0; //$keyword='abc'; if (empty($keyword)) { echo 'Hi'; } else { echo "Hello"; } Hello i have a system where leaders add members, i want to display a table of members WHERE the 'leader' field equals 'myusername' so that leaders only see members they added. when using the WHERE function i get a database empty as the result but when i remove the WHERE function i get all the data returned Code: [Select] include("system/include/session.php"); $myUname = $session->username; echo "$myUname"; function displayMembers(){ global $database; $q = "SELECT * " ."FROM ".TBL_MEMBERS." WHERE leader = '$myUname'"; $result = $database->query($q); $num_rows = mysql_numrows($result); if(!$result || ($num_rows < 0)){ echo "Error displaying info"; return; } if($num_rows == 0){ echo "Database table empty"; return; } echo "<table>\n"; echo "<thead> <tr> <th>Full Name</th> <th>Gender</th> <th>DOB</th> <th>Post Code</th> <th>Email Address</th> <th>Edit User</th> </tr> </thead>\n"; for($i=0; $i<$num_rows; $i++){ $Mprefix = mysql_result($result,$i,"prefix"); $Mfname = mysql_result($result,$i,"firstname"); $Mlname = mysql_result($result,$i,"lastname"); $Mgender = mysql_result($result,$i,"gender"); $Mdob = mysql_result($result,$i,"dob"); $Mpostcode = mysql_result($result,$i,"postcode"); $Memail = mysql_result($result,$i,"email"); echo " <tbody> <tr> <td>$Mprefix $Mfname $Mlname</td> <td>$Mgender</td> <td>$Mdob</td> <td>$Mpostcode</td> <td>$Memail</td> <td> <center> <form action=\"system/admin/adminprocess.php\" method=\"POST\"> <input type=\"hidden\" name=\"deluser\" value=\"$uname\"> <input type=\"hidden\" name=\"subdeluser\" value=\"1\"> <input type=\"submit\" class=\"button plain\" value=\"Edit Member\"> </form> </center> </td> </tr> </tbody>\n"; } echo "</table><br>\n"; } all help i am thankful for Hi all, I need some help. My ob_get_contents() is empty and gives me a empty file everytime. I tried different cache script it is still the same. I have also tried fwrite($fp, 'hello') In this case, it successfully writes to the file. But when i use ob_start and ob_get_contents, it will be empty. can anyone please advice. My simplified script is here <?php // Settings $cachedir = 'cache/'; // Directory to cache files in (keep outside web root) $cachetime = 600; // Seconds to cache files for $cacheext = 'html'; // Extension to give cached files (usually cache, htm, txt) // Ignore List $ignore_list = array( '/rss.php', '/search/' ); // Script $page = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; // Requested page $cachefile = $cachedir . md5($page) . '.' . $cacheext; // Cache file to either load or create $ignore_page = false; for ($i = 0; $i < count($ignore_list); $i++) { $ignore_page = (strpos($page, $ignore_list[$i]) !== false) ? true : $ignore_page; } $cachefile_created = ((@file_exists($cachefile)) and ($ignore_page === false)) ? @filemtime($cachefile) : 0; @clearstatcache(); // Show file from cache if still valid if (time() - $cachetime < $cachefile_created) { //ob_start('ob_gzhandler'); @readfile($cachefile); //ob_end_flush(); exit(); } // If we're still here, we need to generate a cache file ob_start(); ?> All My HTML AND PHP CODES TO RUN THE SITE <?php // Now the script has run, generate a new cache file $fp = @fopen($cachefile, 'w'); // save the contents of output buffer to the file @fwrite($fp, ob_get_contents()); @fclose($fp); ob_end_flush(); ?> I noticed that strtolower() wasn't working. My script was adding blank rows to a text file that was supposed to be lowercase emails, so I wrote the following script to confirm it's not working: <?php $var = "Foo"; echo "$var<br />"; echo srttolower($var)."<br />"; $var = strtolower($var); echo "$var<br />"; ?> This page just prints "Foo" once on the screen where I should see Foo foo foo I then checked my error log, and I'm getting Call to undefined function messages for strtolower(). Any ideas? Hi there, Need a little help here if anyone has the time. In short, I have a page that is dynamic, that sends POST data to a handler, pretty standard stuff. Normally, for me anyway, I know what the field names will be in advance and handle then as usual. In this case the form content is created dynamically from a GUI I created and the names of the fields are suffixed with the product ID. Within the handler I have stripped the POST data down to the main two vars, namely the pid- product ID and qty- quantity ordered and within a loop created a string to explode() like; 9_33_21_66 $oStrArray = explode('_', $ostring); echo "ostring[0] =".$oStrArray[0]; echo "ostring[1] =".$oStrArray[1]; echo "ostring[2] =".$oStrArray[2]; echo "ostring[3] =".$oStrArray[3]; Result => ostring[0] =9 ostring[1] =33 ostring[2] =21 ostring[3] =66 Now, the 1st, 3rd, 5th etc will be the pid and the 2nd, 4th, 6th etc. will be the qty. Only two sets are used in this example, normally 50+ pairs of values will be present. If it helps with the loop that I need to create - if a foreach will not suffice - I can deduce how may pairs will be present and send this as a var via GET from the form setting a value for i, for instance. I need to be able to, within a loop, * pull the first value as a pid * run a subroutine to pull the data from the DB table to get all the product info to display on a confirmation page [this is not ecom - just emailed orders for existing clients] I can do all the MySQL Query stuff it is just rationalising the data extracted from the array Well I am sure you can see from that what I am trying to do, I will need to do the multiplications etc. I do not know how to handle the data in the array created by the explode() In logic I would say this if x in $ostring is even then $ostring is a product id [mysql query to get details from table] next item in array is corresponding quantity - print details of product in a table, do the multiplication to give line total and add to $message ready for email - NEXT pair of vars I really hope that makes sense and someone can point me in the right direction - thanks in advance for any assistance. Regards A I am using a script to take postcodes and give distances between them and list all postcodes within a radius. Where it should list all the postcodes in the radius it provides and empty array - any clues?? the table is 'geodb' relevant fields are postcode place latitude longitude and the code is Code: [Select] if(isset($_GET['Search'])) { $postcode = strtoupper($_GET['postcode']); $radius = $_GET['radius']; echo $postcode .

The for has ALOT of imputs and can also generate new one automaticly using javascript. My problem is that come of them returns empty arrays while other works. Is there a maximum or some kind that a form can submit at the time? i made a print_r on the $_POST var and this is what i got (I tooke out all the other arrays but theres a lot more then what i am posting) [...] print ('<tr> <td> <input type="text" size="9" name="styleenc[]" value=""> </td> <td> <input type="text" size="9" name="couleurenc[]" value=""> </td> <td> <input type="text" size="2" name="c_y[]" value=""> </td> <td> <input type="text" size="2" name="c_a_s[]" value=""> </td> <td> <input type="text" size="2" name="c_a_l[]" value=""> </td> <td> <input type="text" size="2" name="c_a_o_s[]" value=""> </td> <td> <input type="text" size="9" name="descenc[]" value=""> <input type="hidden" size="9" name="invisible3[]" value="3"> </td> </tr>'); [...] Code: [Select] Array ( [styleenc] => Array ( [0] => [1] => [2] => [3] => [4] => ) [couleurenc] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_y] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_a_s] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_a_l] => Array ( [0] => [1] => [2] => [3] => [4] => ) [c_a_o_s] => Array ( [0] => [1] => [2] => [3] => [4] => ) [descenc] => Array ( [0] => [1] => [2] => [3] => [4] => ) [invisible3] => Array ( [0] => 3 [1] => 3 [2] => 3 [3] => 3 [4] => 3 ) [emplacement] => sdcwedf ) They should all have values i don't get it ... the only one that has values is invisible3 that has been manualy specified with value="3" I want to merge some arrays as Code: [Select] $mixing = array_merge($mixedresult1, $mixedresult2, $mixedresult3);but the arrays can be empty sometimes. In this case, I will get an error for the empty array as Code: [Select] PHP Warning: array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #1 is not an arrayHow I can avoid this error by omitting empty arrays? What I am trying to do is to submit as POST values to database_write.php, from within the while statement. What is happening is I am getting the second row of data every time I change the primary button.
Currently database_write.php is just doing print_r($_POST), And my array is always the same, no matter which select box I choose from. How can I get the values to be associated with the row I am currently changing? Any help would be great, thanks.

I am working with the Amazon API, and I am trying to display a default image if a product does not have an image associated with it. The query is coming back as an array. Typically, each product image array looks like this: $d = SimpleXMLElement Object ( http:// => [url]http://ecx.images-amazon.com/images/I/51aUIul6XjL._SL160_.jpg [Height] => 160 [Width] => 112 ) The code goes like this: Code: [Select] if ($d=$E->MediumImage) { $iu=$d->URL; $ih=$d->Height; $iw=$d->Width; echo count($d); if (strlen($iu) > 0) {echo "<center><a href='$url' target='_blank'><img src='images/amazon_noimage.jpg' width='175' height='175' border='0'></a></center>";} else {echo "<center><a href='$url' target='_blank'><img src='$iu' width='$iw' height='$ih' border='0'></a></center>";} } However, images/amazon_noimage.jpg never shows up (even though it is linked correctly, as I've tested this link). I have tried the following: if (strlen($iu) > 0) if (count($iu) > 0) if (strlen($d->URL) > 0) if (count($d->URL) > 0) if (isset($d)) if (!isset($d)) etc ... If I display the following, where there is no image, I get nothing displayed: echo $iu; print_r($iu); echo $d->URL; etc ... However, if there is an image, I get a link, such as the following: http://ecx.images-amazon.com/images/I/51c2BFpDN0L._SL160_.jpg There seems to be NOTHING that I can do to trigger the 'ELSE' part of the if statement. This is a total enigma to me ... any ideas?? Hi

<form name="test" method="post" action="test.php"> <label for="quest"> <input type="text" name="quest" /> <!-- REQUIRED --> </label> <label for="answers"> <input type="text" name="answers[]" /> <!-- REQUIRED --> </label> <label for="answers"> <input type="text" name="answers[]" /> <!-- REQUIRED --> </label> <label for="answers"> <input type="text" name="answers[]" /> </label> <label for="answers"> <input type="text" name="answers[]" /> </label> <label for="answers"> <input type="text" name="answers[]" /> </label> <label for="submit"> <input type="submit" name="submit" value="Submit" /> </label> </form>Following function working only on all empty input fields, i need help to enable button when required fields is not empty.
$(document).ready(function() {
var $submit = $("input[type=submit]"),
$inputs = $('input[name=quest], input[name=answers[]]');
function checkEmpty() {
// filter over the empty inputs
return $inputs.filter(function() {
return !$.trim(this.value);
}).length === 0;
}
$inputs.on('keyup', function() {
$submit.prop("disabled", !checkEmpty());
}).keyup(); // trigger an initial blur
});
Hi All, Need help. I'm strugling to figure out how to write the code to display default image if no image is available. I'm able to display image if data is available. Not able figure how to echo if/else statment. Below is the code Code: [Select] <?php function perDetails($var1, $result, $var2){ $dft_img = 'lib/images/name.png'; echo '<div class="desc">'.$var1.'</div>'; $color="1"; echo '<table align="center" cellpadding="2" cellspacing="1">'; while($row = mysql_fetch_array($result)){ $id = $row['pid']; $name = $row['pname']; $img = $row['pphoto_localurl']; $poster = str_replace("./", "lib/", $img); if($color==1){ echo '<tr bgcolor="#FFC600"><td><img src="'.$poster.'" width="32" height="42" alt="'.$name.'"</td><td><a href="persons.php?det='.$var2.'&perid='.$id.'"> '.$name.'" </a></td></tr>'; $color="2"; } else { echo '<tr bgcolor="#C6FF00"><td><img src="'.$poster.'" width="32" height="42" alt="'.$name.'"</td><td><a href="persons.php?det='.$var2.'&perid='.$id.'"> '.$name.'" </a></td></tr>'; $color="1"; } } echo '</table>'; } ?> i am trying to check if the array element (which would be a file) is null or not. when i run it, uploading one file, it says "Please select some files to upload first!" X 3. what am i doing wrong? my code: http://pastebin.com/m0k3fEd2 Hi, i'm new here and hope i've finally found a forum where i can find the perfect solution for my questions.
Well since a year now i started to work with PHP and still now and then there are some things where i seize on. My question is on of those situations.
I have the following code:
if (isset($_POST)){
foreach ($_POST as $key => $value){
if (!empty($value)){
$update_rma_detail_stmt = $dbh->prepare("UPDATE rma_detail SET $key = ? WHERE rd_rma_nr = ?");
$update_rma_detail_stmt->bindParam(1, $value);
$update_rma_detail_stmt->bindParam(2, $getadmrmaid);
$update_rma_detail_stmt->execute();
}
}
}
All i want is when there is an empty (not filled in) input field because it is not mandatory the foreach still continuous to the end.
When i use
if (!empty($value)){
It still outputs these error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 1366 Incorrect integer value: ' '
However, when i dont use i got an other error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect date value: ''
It is however so that the datetime is the very first empty field it come across when looping. I think my if (!empty($value)){ is doing the right thing but still gives error's on integers. Can it be? I allready tried to use trim() or array_filter() but because i previously never used it i dont know if i am doing it the right way so any help is welkom!
Thanks!
