PHP - Object Checking - (get_file_contents)
So I'm reading a JSON, and I'm using the command GET_FILE_CONTENTS, and I'm getting results. However, the JSON is incomplete to a point where in some instances the variables/objects within do not always contain a certain array.
Issue; I'm getting errors returned when that particular array does not exist. The code below is the line that's getting the error returned because the TAGS[0] doesn't exist in all instances. Question; How do I check if the array exists within the GET_FILE_CONTENTS object? See example; Code: [Select] If($dall->tags[0]->name==$catgrp) Error: Notice: Undefined offset: 0 in /var/www/vhosts/website/httpdocs/testjson/index.php on line 63 Notice: Trying to get property of non-object in /var/www/vhosts/website/httpdocs/testjson/index.php on line 63 Similar TutorialsI'm trying to create an online web editor. It works fine for opening and writing files on the same server where the web editor is hosted, but I want it to be able to get_file_contents, fopen and fwrite files on a remote server, logging in with ftp_connect and ftp_login. I've noticed the functions ftp_get and ftp_fget but I'd rather not create another local file, if possible I want to open the remote file directly into a <texarea> then save it directly back to the remote server. Is this possible? So far I just get errors... Here's an example of the code I'm trying to combine, to retrieve the contents of a file on a remote server and put them in a <textarea>: Code: [Select] <?php $conn = ftp_connect("ftp.domain.com"); ftp_login($conn, "username", "password"); ftp_pasv($conn, true); $filename='example.php'; // open file $fh = fopen($filename, "r") or die("Could not open file!"); // read file contents $datax = fread($fh, filesize($filename)) or die("Could not read file!"); $data=htmlspecialchars($datax); // close file fclose($fh); // close this connection ftp_close($conn); echo '<textarea cols="200%" rows="50">'.$data.'</textarea>'; ?> And another failed example: Code: [Select] <?php $filename='editor.php'; $fh = fopen("ftp://username:password@domain.com/example.php", "r") or die("Could not open file!"); $datax = fread($fh, filesize($filename)) or die("Could not read file!"); $data=htmlspecialchars($datax); fclose($fh); echo '<textarea cols="200%" rows="50">'.$data.'</textarea>'; ?> Hi. I have php code that attempts to read a file into a string using get_file_contents(), but it claims the file does not exist. I do the same thing in another php file (same directory) and it works. Only difference is that the first file has the call in a function. File one: Code: [Select] $email_template = "../email_templates/new_instructor.html"; echo file_exists($email_template); $message = file_get_contents($email_template);//get the email template File two: Code: [Select] $email_template = "../email_templates/new_instructor.html"; echo file_exists($email_template); echo file_get_contents($email_file); please help.' thanx Hey all, I want to have an object that has a property which is an object containing instances of other objects. I try this: Code: [Select] class Blog extends Posts { public $has_posts; public function __construct($a,$b,$c){ $has_posts = (object) array_merge((array) $a, (array) $b, (array) $c); } } class Posts { public $b; public function __construct($b){ $this->b = $b; } } $post1 = new Posts(1); $post2 = new Posts(2); $post3 = new Posts(3); $blog = new Blog($post1,$post2,$post3); var_dump($blog->has_posts); //null foreach($blog->has_posts as $post){ //Invalid argument supplied for foreach() echo $post->b; } But as you see, has_posts is null, not an object containing other objects. Thanks for response. I have a Soup object in a Bowl object in a Microwave object. The Microwave object has the methods: receiveItem(Bowl $b) cookItem(???) I want the Microwave to be able to set the Soup->temperature but I'm not how to do that? Make sense? TomTees Scenario: each row contains an ID, title, description, price, and up to 5 images. There are not always 5 images stored in each row. The images are stored as a file path which is then pulled out of the DB and used to display an image via HTML. I need to do some sort of loop/check that looks at the contents of a particular row (actually all rows in this particular table) and then decide how many times to loop through the images to display them all correctly on the webpage. I could statically set a variable for each column but then it would have a space for an image but nothing would show. I really want this to be able to only load the images that are stored in the DB. Any help on how I can go about this? thanks -beemer Hi friends I have following code Code: [Select] function UseOfSSL($domain_name) { $site = ($domain_name); $port = 443; $fp = fsockopen($site,$port,$errno,$errstr,10); if(!$fp) { echo "Not Installed"; } else{ echo "Yes, it is installed"; fclose($fp); } } If domain name from $domain_name has installed SSL, it will show it is installed else not installed. Problem is that I tried this with both types of sites, those who are using SSL and those who are not and always, it says Yes, it is installed. 443 is used because https uses port 443 What is the cause ? So basically I have a site, and on that site, I have a page that submits a form and updates a database. I have it set up so that someone can enter in Multiple values into a textarea, one on each line, and it will submit each of those values as a new row in the database, but for the life of me, I cannot figure out how to check those values against the actual users. It is basically a point system, where the staff can award points users of the site. But at the moment, a Staff member could enter in Jibberish, and it would insert that into the database, but I want it to check my users table to make sure the user exists before it inserts it into the database. here is my code: <?php include 'global.php'; echo $headersidebar; if ($_COOKIE['access'] == $accessstaff) { if(count($_POST)) { $array = preg_split('/(\r?\n)+/', $_POST['studentname']); foreach($array as $students) { $statusmsg = '<center><span style="background: #A6FF9E;">You have successfully submitted points to the database.</span></center>'; mysql_query("INSERT INTO points (giver, receiver, points, category, reason, date, status) VALUES ('{$_COOKIE['username']}', '{$students}', '{$_POST['pointamt']}', '{$_POST['pointcat']}', '{$_POST['pointreason']}', '{$date}', 'Validating')"); } } $addpointspage = $statusmsg . ' <form action="submit_points.php" method="post"> <table class="table" > <tr> <td colspan="10"> <h1><strong><center>Submit Points</center></strong></h1> </td> </tr> <tr> <td colspan="10" rowspan="100"> <center>Please remember to follow the house point limits when submitting house points.</center> </td> </tr> </table> <table class="table"> <tr> <td style="width: 15%;" valign="top"> Student Name:<br> <span style="font-size: 60%;">(List as many as you want; One per Line)</span> </td> <td colspan="10"> <center><textarea name="studentname" cols="60" rows="10"></textarea></center> </td> </tr> <tr> <td style="width: 15%;" valign="top"> Amount of Points: </td> <td> <input style="position: relative; left: 16px;" type="text" size="15" name="pointamt" /> </td> <td> Do not put anything that is not a number into this box. </td> </tr> <tr> <td style="width: 15%;" valign="top"> Point Category: </td> <td colspan="10"> <select name="pointcat" style="position: relative; left: 16px;"> <option SELECTED value="">-------</option> <option>Class Work</option> <option>Class Exam</option> <option>Extra Work</option> <option>Contests</option> <option>Teacher\'s Assistant</option> <option>Negative Points</option> </select> </td> </tr> <tr> <td style="width: 15%;" valign="top"> Reason: </td> <td colspan="10"> <input style="position: relative; left: 16px;" name="pointreason" type="text" size="80" /> </td> </tr> <tr> <td> </td> <td colspan="10"> <input style="position: relative; left: 16px;" type="submit" value="Submit Points" /> </td> </tr> </table </form> '; } elseif (1==1) { $addpointspage = $accessdenied; } echo ' <!-- start content --> <div id="content"> <div class="post"> <div class="entry"> <p><strong>' . $addpointspage .

I need to query a database for a starting time for a meeting, and if the start time is at 7pm, I need to allow access to a page from 6pm til 11pm. Not a problem. The problem lies when the ending time (4 hours after the start time) crosses over to a new day. Here's what I have: Code: [Select] <?php elseif ($row['meeting'] == "7:00pm") { $starthour = 18; $endhour = 23; } elseif ($row['meeting'] == "8:00pm") { $starthour = 19; $endhour = 0; } if ($thishour <= $endhour && $thishour >= $starthour) { include "meeting_ok.php"; } else { echo "Meeting room is unavailable at this time...."; } ?> The "0" for endhour is throwing things off. How should I best account for a new day? Thanks! I don't know precisely how to put it so i will give an example: suppose you have a search form with input fields for: -an age range, -a data range, -for the sex, -postal code as soon as the user would fill in one of these input fields, a query should be generated including a condition doing something with the inputted value. For example, the user fills in maxAge, the the query should say: SELECT * FROM table WHERE age >= maxAge; Filling more than one criterion then would do .= " AND criteria (condition) inputvalue " etc... My question comes to the part about: how to check if there is already a WHERE in the clause and how to put WHERE or AND for every criterion. Since doing like above, i won't be able to search for another criterion if i don't select maxAge first because then there would be no WHERE in the sql clause. Hopefully i've put it clear thanks in advance Hello all, it's been a while! Good to be back. I am having trouble with a script I'm trying to modify to seach for domains with specific extensions. Now, I have never done any domain checking before and I'm a little bewildered. The script uses an array and checks the input against each extension using the array. Each line looks similar to: Code: [Select] '.com' => array('whois.crsnic.net','No match for'), What does the whois.crsnic.net mean? I assume it's a register/database of domains? $characterIDs = explode(',', $_POST['characterIDList']); After the explode I want to take all those values and do a select statement in a database table for any of the values that match any of the values inside that variable variable. Not sure how to do this since there is no limit to how may there could be. I have written the code for email check, but how and where can I put the code to check if a username has been used twice? Thanks in advance. Code: [Select] <?php $servername = "localhost"; $username = ""; $password = ""; //validate fields if(!$_POST["username"] || !$_POST["email"] || !$_POST["password1"] || !$_POST["password2"]){ echo "<p> </p><p> </p><p> </p><br />Please fill the required fields, <p> </p><p> </p><a href='register.php'>Go to register page</a>"; //validate password }else if($_POST["password1"] != $_POST["password2"]){ echo "<p> </p><p> </p><p> </p><br />Please go back, PASSWORDS do not match! <p> </p><p> </p><a href='register.php'>Go to register page</a>"; //validate email }else if(!(eregi("^.+@.+\\..+$", $_POST['email']))){ echo "<p> </p><p> </p><p> </p><br />Please enter a valid EMAIL! <a href='register.php'><p> </p><p> </p>Go to register page</a>"; //validate captcha }else if(($_SESSION['security_code'] != $_POST['security_code']) || (empty($_SESSION['security_code'])) ){ echo "<p> </p><p> </p><p> </p><br />CAPTCHA CODE does not match! <p> </p><p> </p><a href='register.php'>Go to register page</a>"; }else{ $conn= mysql_connect($servername,$username,$password)or die(mysql_error()); mysql_select_db("genesis_members",$conn); // check if already registered $sql_check = "SELECT * FROM users WHERE email = '".$_POST[email]."'"; $result_check = mysql_query($sql_check,$conn) or die(mysql_error()); $row = mysql_fetch_assoc($result_check); if($row['id']){ echo "<p> </p><p> </p><p> </p><br />EMAIL already registered! <p> </p><p> </p><a href='register.php'>Go to register page</a>"; }else{ // insert in db $sql = "INSERT INTO users (username, email, password, company, phone, services) VALUES ('".$_POST[username]."', '".$_POST[email]."', '".$_POST[password1]."', '".$_POST[company]."', '".$_POST[phone]."', '".$_POST[services]."')"; $result = mysql_query($sql,$conn) or die(mysql_error()); echo "<p> </p><p> </p><p> </p><br /><h1>You Have Successfully Registered</h1>"; echo "<p> </p><p> </p><br /><a href='main_login.php'>go to login page</a>"; } } ?> I coded small funny script I tested it in three hosting ww.rufaa.net dallawat.com/new ibuj.org but I don't know why in the first link, my script seem slow not like the other second and third links php5.2, mysql server5.02: if record exists,append random digit to end of information in rows column then add to database If user mike already exists and another mike is trying to create a user id I would like to keep the old mike record like it is, then add a new mike record, but add a unique digit to the end of the name mike before the record gets added to the database as a new row. Thank you kindly! can somebody please tel me how to make sure a field is a number? I have some error checking like if(empty($postcode)) { $errors[] = "Please enter your postcode"; } if(strlen($tel)<11) { $errors[] = "Please enter a phone number that is the correct length"; } But I dont know and cant find how to check for a number only. Hey In my spare time, I am working on my PHP framework. Now, to help with development and quickly discover where I miss a type cast, I have adopted to check all parameters that are passed to a method using a function. For instance: public function __construct(&$target = null, $depth = 1){ $this->validateArguments( array(1 => 'int'), array(1 => $depth) ); And the code that triggers the exception: public function testPhpFreakType(){ $obj = 1; $p = new Xcms_DataStructures_Pointer($obj, "1"); } Code: [Select] 0: |--------------------------------------------------| 1: |--Exception: 4cfe2e86ca5970.22624423 - Full Trace | 2: | Tue, 07 Dec 2010 13:54:30 +0100 3: |-Class: 4: | Xcms_Exceptions_InvalidArgument 5: |-Message: 6: | Argument #1 of Xcms_DataStructures_Pointer:__construct() is no _null:int 7: | Stack offset: 3 8: | 9: |-Trace 10: | #0 D:\www\xcms_rev\core\exceptions\invalid.argument.helper.class.php(133): Xcms_Exceptions_InvalidArgumentHelper::factory(1, '_null:int', NULL, 2) 11: | #1 D:\www\xcms_rev\core\basic.class.php(80): Xcms_Exceptions_InvalidArgumentHelper::validateArguments(Array, Array, Array, 1) 12: | #2 D:\www\xcms_rev\core\data.structures\pointer.class.php(49): Xcms_Basic->validateArguments(Array, Array) 13: | #3 D:\www\xcms_rev\core\data.structures\pointer.test.php(73): Xcms_DataStructures_Pointer->__construct(1, '1') 14: | #4 [internal function]: Xcms_DataStructures_PointerTest->testPhpFreakType() 15: | #5 C:\xampp\php\PEAR\PHPUnit\Framework\TestCase.php(737): ReflectionMethod->invokeArgs(Object(Xcms_DataStructures_PointerTest), Array) 16: | #6 C:\xampp\php\PEAR\PHPUnit\Framework\TestCase.php(627): PHPUnit_Framework_TestCase->runTest() 17: | #7 C:\xampp\php\PEAR\PHPUnit\Framework\TestResult.php(629): PHPUnit_Framework_TestCase->runBare() 18: | #8 C:\xampp\php\PEAR\PHPUnit\Framework\TestCase.php(575): PHPUnit_Framework_TestResult->run(Object(Xcms_DataStructures_PointerTest)) 19: | #9 C:\xampp\php\PEAR\PHPUnit\Framework\TestSuite.php(766): PHPUnit_Framework_TestCase->run(Object(PHPUnit_Framework_TestResult)) 20: | #10 C:\xampp\php\PEAR\PHPUnit\Framework\TestSuite.php(742): PHPUnit_Framework_TestSuite->runTest(Object(Xcms_DataStructures_PointerTest), Object(PHPUnit_Framework_TestResult)) 21: | #11 D:\www\xcms_rev\core\testing\manager.class.php(83): PHPUnit_Framework_TestSuite->run() 22: | #12 D:\www\xcms_rev\core\testing\manager.class.php(56): Xcms_Testing_Manager->testClass(Object(ReflectionClass)) 23: | #13 D:\www\xcms_rev\cache\pkg\scripting\script_1.php(3): Xcms_Testing_Manager->run(Object(Xcms_Url_DefaultRequest)) 24: | #14 D:\www\xcms_rev\core\util.lib.php(340): include('D:\www\xcms_rev...') 25: | #15 D:\www\xcms_rev\core\packages\scripting\controllers\scripting.controller.php(66): Xcms_Util::sandboxedInclude('cache/pkg/scrip...', Array) 26: | #16 D:\www\xcms_rev\core\mvc\controllers\default.controller.php(210): Xcms_Packages_Scripting_Controllers_ScriptingController->execute(Object(Xcms_Packages_Scripting_Models_ScriptModel), Object(Xcms_Templating_Context)) 27: | #17 D:\www\xcms_rev\core\mvc\controllers\default.controller.php(170): Xcms_Mvc_Controllers_DefaultController->runScript(1, 0, Object(Xcms_Templating_Context)) 28: | #18 D:\www\xcms_rev\core\mvc\controllers\default.controller.php(132): Xcms_Mvc_Controllers_DefaultController->runScripts(0, 0, Array, Array, 1, 0) 29: | #19 D:\www\xcms_rev\index.php(15): Xcms_Mvc_Controllers_DefaultController->run() 30: | #20 {main} 31: |--------------------------------------------------| I think this speeds up my development quite a bit, because I can catch errors very early in the development process. I can give multipe possibilities of what is allowed for each parameter, not just a single possibility. Also, it is possible to register custom type/validity-checks on both global and local scope. One thing I do worry about, however, is the the performance. Of course, I could just make the funciton do nothing in production code, if it takes too much time, or I could write a script to remove all calls to that function. When I started learning python a while back, the concept to just code to interfaces instead of types seemed very intuitive and made my code much more flexible. Of course that is what I do with PHP as well, but I it's not entirely the same. So now, coming back at my PHP code and having introduced features of static languages such as type checking, I worry about whether that is the right approach. What are your thoughts on the matter? Okay I need some help. I want to check a MySQL DB and then if it says 0 then don't do anything if it says anything else echo out what's there. I have tried for about a hour now. I have two arrays of keywords that I'm pulling from the database. I'm wanting to compare those two arrays and see if ANY of the contents are the same, if they are push that result into another array for later use. while($row_rsCWGetupsell = $cartweaver->db->db_fetch_assoc($rsCWGetupsell)) { $b = array_unique(array_filter(explode(",", preg_replace( '/\s*/m', '', $row_rsCWGetupsell["product_keywords"])), "strlen")); $a = array_unique(array_filter(explode(",", preg_replace( '/\s*/m', '', $row_rsCWGetProduct["product_keywords"])), "strlen")); if($a IN $b) // <--- this is where the comparison should be! $list[] = $row_rsCWGetupsell; } Hi, I'm creating an upload section that limits users to upload the following file types: .zip .rar .doc .jpeg .gif When getting the type for .pdf files, it comes up as: application/force-download and for .rar files it comes up as: application/x-download If I do a check that says: if ($type=="application/force-download" || $type=="application/x-download") then will users only be able to upload .PDF and .RAR files? I'm assuming these two types will allow other formats as well. If this is the case, how can I check the extension of the file before the user is able to upload it. I was thinking of somehow capturing the last 3 letters of the filename, and then doing the check that way, except I'm not sure how to go about this. Any insight appreciated! Can someone help me to get this code working... Code: [Select] public function getBowlContents(){ if is_null($this->contents) { return "The bowl is empty!"; } else { return "The bowl contains " . $this->contents . " soup!"; } TomTees |
