PHP - Empty Results Check Not Working...
Been trying to find an answer and keep running around in circles...
I have: ( left test echos in there) if ($r['left_house_number'] != '') { /* Now see what they are supposed to get */ $left_customer_query = "SELECT * FROM customer WHERE house_number ='".$r['left_house_number']."' AND street = '".$r['left_house_street']."' AND route_number = '".$_SESSION['route_number']."'"; // echo "SELECT * FROM customer WHERE house_number ='".$r['left_house_number']."'

AND route_number = '".$_SESSION['route_number']."'"; $left_customer_result = mysql_query($left_customer_query) or die(mysql_error()); $left_customer_result_count = mysql_num_rows($left_customer_result); echo $r['left_house_number'].' =lhn1'; while ($lrow = mysql_fetch_array($left_customer_result)) { echo $r['left_house_number'].' =lhn2'; /* See if there is any customer if not display blank row */ echo $left_customer_result_count.' = count '; if ($left_customer_result_count < 1) { echo $r['left_house_number'].' =lhn3'; echo '<span class="delivery_nothing">'.$r['left_house_number'].' </span> 1<span class="delivery_nothing">'.$r['left_house_street'].' '; } else { /* Have a customer, now check to see if they are supposed to get something */ if ($lrow['status'] != "AC" && $lrow['status'] != "VH") { /* Customer is stopped or on vacation so show house number and street not bolded */ echo '<span class="delivery_nothing">'.$r['left_house_number'].'</span>2<span class="delivery_nothing">'.$r['left_house_street']; echo $r['left_house_number'].' =lhn4'; } else { /* Now check for correct delivery day and return data */ if (Show_Product($lrow['product']) == '1') { echo $r['left_house_number'].' =lhn5'; echo '<span class="delivery_bold">'.$lrow['house_number'].'</span><span class="delivery_bold">'.$lrow['placement'].'</span><span class="delivery_bold">'.$lrow['street'].'</span>'; echo Product_Formater($lrow['product']); } I have tried... if ($left_customer_result_count < 1) { if ($left_customer_result_count == 0) { if ($left_customer_result_count == '') { if ($left_customer_result_count === 0) { And I can't get it to work. the count "test echo" is either blank or 1 If I echo the sql statement with values I know aren't in the db and paste it into phpmyadmin: SELECT * FROM customer WHERE house_number = '3333' AND street = 'Chili Avenue' AND route_number = '68-24-630' I get: "MySQL returned an empty result set" And if I change it to something that is in the db: SELECT * FROM customer WHERE house_number = '3019' AND street = 'Chili Avenue' AND route_number = '68-24-630' I get: "Showing rows 0 - 0 (1 total, Query took 0.0012 sec)" So what do I have to do to get this to work right? What does it actually output when there are no results returned? thanks, Similar Tutorialsi am pulling the login date from the databases and i want it to check if the variable is empty and if it is echo Never Loged In and if it not empty echo the date <?php include'db.php'; $id=$_GET['id']; $sql=mysql_query("SELECT * FROM admin WHERE id='$id'")or die(mysql_error()); while($row=mysql_fetch_array($sql)) { $date=$row['login_date']; if($date > 0) { echo"Never Loged In"; } else { echo"$date"; } } ?> I have the form / script below that works to add multiple rows of data with one query. One thing I did not think about is what if the first set of form fields are filled and the second is not. Currently the script insert an empty row. I'm sure how I would go about checking for an empty row and if there is an empty row ignore it and do not put it in the DB. Can someone point me in the right direction?

On the php page that processes the form, I want to check first to make sure the user entered something (input field is not empty) before processing the form. I'll just provide a skeleton of form processing page below. *(I'm save space and time by omitting the form itself but he text inputs fields have the following name attributes "name", "company", "email", and the textarea field's name attribute is "message" ) I'll do my best to explain the code in further detail within the code comments. Code: [Select] <?php //Turn on output buffering. Allows for headers to be called anywhere on script. See pg228 Ulman. ob_start(); if (isset($_POST['submit'])) { // Initialize a session to keep tract of error and success messages: session_start(); //Define a session variable that keeps tract of how many times user accesses page. $_SESSION['views'] = 1; // Connect to the database. require('config/config.php'); //Check for errors. //Check to make sure they entered their name. if (!empty ( $_POST['name'])) { $a = TRUE; } else { $a = FALSE; //This variable will be echoed on the form if field is missing a value $_SESSION['name'] = '*Please enter a valid name.'; } //Check to make sure they entered their company name. if (!empty ( $_POST['company'])) { $b = TRUE; } else { $b = FALSE; //This variable will be echoed on the form if field is missing a value $_SESSION['company'] = '*Please enter the name of an institution you are affiliated with.'; } //Check to make sure email is valid. if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $_POST['email'])) { $c = TRUE; }else { $c = FALSE; //This variable will be echoed on the form if field is missing a value or email format is wrong. $_SESSION['email'] = '*Please enter a valid email address.'; } //Check to make sure they entered their message. if (!empty ( $_POST['message'])) { $d = TRUE; } else { $d = FALSE; //This variable will be echoed on the form if field is missing a value $_SESSION['message'] = '*Please enter your message.'; } //If no errors if (empty($_SESSION['name'] ) && empty($_SESSION['company'] ) && empty($_SESSION['email'] ) && empty($_SESSION['message'] ) ) { //Insert data into database. $query = "INSERT INTO table... ; $result = mysql_query($query) or die("Data could not be inserted into table because: " .mysql_error()); if (mysql_affected_rows() == 1) { // Display success message //This variable will be echoed on the form if everything is filled out correctly. $_SESSION['sent'] = "Your email has been sent. We will get back to you shortly."; // Display contact page (the page containing the form) header("Location: contact_page.php"); exit(); }else{die(mysql_error());} //Display error messages. } else {// if errors array is not empty // Display page (page containing the form) header("Location: contact_page.php"); exit(); }//End of if there are errors. }//End of if submit. ?> So there it is. Everything works fine except that the part which checks if the textarea (named "message") is empty, doesn't work. If I click the submit button without filling out any field, the appropriate error messages are printed for the text input fields but not the text area field. If I fill out all fields correctly and leave the "message" field blank, the form gets processed correctly and values are placed in the database and the success message is printed out. This is also the case when I enter a value for "message" textarea field. Now I tried something. I changed the textarea to a text field and the $_SESSION['message'] variable finally got echoed when I left this field blank. So apparently, the problem arises from the fact that the named attribute from a textarea tag is not being processed correctly?? Who knows what's going wrong here? Ok so i have registration page on my webs but i didn't work on empty fields so how could i check all fields? Code: [Select] //if no name if(!$name){ $error = "Username missing."; } //if no pass if($pass == false){ $error = "$error,Password missing"; } //if no pass conf if($pass_conf == false) { $error = "$error,Pass conf missing."; } //if no email if($email == false){ $error = "$error,Email missing."; } //pass conf if($pass != $pass_conf){ $error = "$error,Passwords do not match."; } echo "<script>alert('$error');</script>;"; //header("Location: register.php"); My script gives same results every time (even if i fill any of fields)...also if i un-comment header command it wont show alert..it just reloads the page So can anyone help me with this? Thanks.. I have two array, how I can have if else to check if both array1 and array2 are empty? if (empty both arrays) { } else { even if one of them are not empty } Hello: I'm trying to figure out how to NOT show emailed results if the checkbox is empty (not checked). I only want it included in the message of the email if the checkbox was checked. It is writing the data to the email properly, but it is including some of the code as well. This is my email code: Code: [Select] mail( "me@digital.com", "Sign-up Sheet Request", "Date Sent: $myDate\n Parent's Name: $ParentsName Best Phone: $BestPhone Email: $Email Student's Name: $StudentsName Student's School: $StudentsSchool\n\n if(trim($SATTest1) != \"\" ) { echo \"$SATTest1\"; } ", "From: $Email" ); The "$SATTest1" data is displaying properly in the emails, but so is some of the code. Like this: Code: [Select] if(trim(Reading and Math Classes for March 10) != "" ) { echo "Reading and Math Classes for March 10"; } Any idea how to correct this? Thanks! Hi i would like to know what is the best way to check if a textarea or an input box is empty. Is the empty function effective? Code: [Select] Array ( [Comment] => Array ( [post_id] => 1 [name] => cc [email] => [body] => spam ) ) How can i check if email is empty or not? Is there any php built in function? Should i use foreach? Now this one is a bit of a shit head. I am using a really comprehensive class i found on on the web for upload / re-size / crop but i want to be able to override it's error handling and i am not good enough to start modifying the code in the class with out fucking it up. Firstly i will show you how i have invoked the class. Code: [Select] if( isset($_FILES['image'] ) ) { //Class includes include("../scrips/php/cms/database.insert.class.php"); include ("../scrips/php/cms/img.upload.resize.crop.class.php.php"); //----------|Start: upload, resize & save $your_image = new _image; //----------| Upload orginal image $your_image->uploadTo = 'uploads/'; $upload = $your_image->upload($_FILES['image']); //----------| Resize and upload small thumbnail $your_image->newPath = 'thums/'; $your_image->newWidth = 50; $your_image->newHeight = 50; $resized = $your_image->resize(); //----------| Resize and upload medium thumbnail $your_image->newPath = 'thums2/'; $your_image->newWidth = 100; $your_image->newHeight = 100; $resized = $your_image->resize(); //----------| Getting the image name to insert into the database futher on in the code $name = $resized; $img_str = explode("/",$name); $final_img_name = $img_str['1']; echo "Article has been added!"; //----------------|end //----------------| Start database insert (class manipulation) $table = "blog_posts"; $title = "'".$_POST['ArticleTitle']."',"; $img = "'".$final_img_name."',"; $post = "'".$_POST['ArticleBody']."',"; $aurthor_id = "'1',"; $category_id = "'".$_POST['Category']."',"; $date_posted = "NOW()"; $values = array("$title","$img","$post","$aurthor_id","$category_id","$date_posted"); $fields = array('title,','img,','post,','aurthor_id,','category_id,','date_posted'); $obj= new DatabaseInsert; $obj->DatabaseConnectionRequire(); $obj->ArticleInsert($values,$fields,$table); //----------------|end } As you can see it's fairly basic. What i want to do is before it runs this script and starts including/invoking the class etc, i want to be able to check to see if there is a value been posted from a FILE FORM OBJECT and if there is to proceed with this script, alternatively i want it to execute another code which will handle it in regards to the concept of my page. A simple javascript alert with be ok providing it reloaded the page to it's default state. If any one can help me here i would appreciate it a lot. Thanks Hey guys, Really dumb question, but I want to check if a bunch of variables are all not empty. Then, if they aren't, I want to execute a mySQL query. Right now I have this which I know is wrong because it doesn't work the right way: Code: [Select] if($album != null || $artist != null || $year != null || $genre != null) { // stuff here... } Obviously I want all of those variables to be checked if they are empty or not. I did a quick Google and found that checking if the variables are null wouldn't be the correct way of solving this situation because an "empty string" is still not null? Anyway, any help would be appreciated. I'm pretty sure it's really simple :p. 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 I haven't coded in PHP for a while and I'm trying to refresh my memory on some things. =( I was hoping someone here could help me with a problem. I have a script I made to post articles to my database, one of the columns includes a number. 1 (yes) and 0 (no). Now i'm using this to keep track of what articles have been approved. When I edit an article I want to include a check box. If my database field contains 1 its checked... if its 0 then its not checked. how would I go about doing that? This topic has been moved to Application Design. http://www.phpfreaks.com/forums/index.php?topic=347295.0 I'm working on a directory component and have kind of a tricky thing I need to do. The list of results pop through ajax on the left side along with it's google map number tag, and the google map pops on the right side. To make it even trickier the results are popped through a radius search by proximity. The problem is if there are multiple results with the same address you end up having all of the number tags on the map buried under the last tag with that address, plus it makes for kind of a long list. What I need to do is run a check to see if the previous result is the same address, and if yes not pop that result in a new table cell, rather stick it in a jquery drop down div so that all of the following results with the same address are stuffed in the jquery drop down in the same table cell under the first result with that address. In a perfect world all of the listings with the same addresses would be submitted in order so I could just do a check for the previous itemid's address, but of course that's not the case. I thought about running a query to grab ALL of the addresses and then check the item's address against it to see if it matches and if yes echo the jquery div instead of the <td>, but obviously that won't work because that will cause the first item with that address to be put in the div also. Plus I don't know if that's a very efficient way to go about it anyway. Here's kind of the basic thing I'm working with: Code: [Select] $query = "SELECT data_txt FROM jos_sobi2_fields_data WHERE fieldid = 76 AND itemid = $mySobi->id"; $result = mysql_query($query) or die(mysql_error()); while($row = mysql_fetch_array($result)){ $myaddress = $row['data_txt']; } echo "<td $style>"; Any ideas? Hi all, I have a situation here. Currently when a user register himself using our registration form, and did not select any subjects under 'Pre-School' level, the header still appears while retrieving out their details via web, rightfully speaking, it should not show any values, not even the 'Pre-School' header. However the situation now is, even if the user did not make any selections, the header of 'Pre-School' will still appear. How do I code in such if there is no value in Pre-School, it shouldn't even show the header? Should I use (!empty) command? Below is my (!empty) command code, it did not work. All suggestions are greatly welcome! Error Code - (!empty) command Code: [Select] //Pre-School echo '<span class="row_header">Pre-School</span><br/>'; while($row3 = mysqli_fetch_array($data3)) { if (!empty($row3['level_id'] == 1)) { echo ''.$row3['subject_name'].', '; } } echo '<br/><br/>'; Current complete workable code, without (!empty) command, however the 'Pre-School' header still appears Code: [Select] <?php //Pre-School echo '<span class="row_header">Pre-School</span><br/>'; while($row3 = mysqli_fetch_array($data3)) { if ($row3['level_id'] == 1) { echo ''.$row3['subject_name'].', '; } } echo '<br/><br/>'; mysqli_data_seek($data3, 0); //Lower Primary echo '<span class="row_header">Lower Primary</span><br/>'; while($row3 = mysqli_fetch_array($data3)) { if ($row3['level_id'] == 2) { echo ''.$row3['subject_name'].', '; } } echo '<br/><br/>'; mysqli_data_seek($data3, 0); // Move internal result pointer back to first record. //Upper Primary echo '<span class="row_header">Upper Primary</span><br/>'; while($row3 = mysqli_fetch_array($data3)) { if ($row3['level_id'] == 3) { echo ''.$row3['subject_name'].', '; } } ?> 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? On all my forms, after I send an empty string to one field, it will stop accepting values when I resubmit. My code passes through the W3C validator Any ideas?? Hello Everyone, I am having issues where people are submitting null characters on my website (I.e. %00). Currently, I check if their is a value by using the empty function, and I also am checking if the value after running the trim command is =="". How can I check for these special characters to make sure that whatever they are submitting actually contains some sort of legitimate value? Thanks! I have developed a code for a login and seems to work well (No syntax error according to https://phpcodechecker.com/ but when I enter a username and a password in the login form, I get an error HTTP 500. I think that everything is ok in the code but obviously there is something that I am not thinking about.
