PHP - Can Anyone Help (php, Json And Mysqli)
I was pointed in this direction by a friend so firstly, hello
I'm having some teething problems (basically can't get my head around it) and wondered if anyone would be able to have a look at a script for me (beer money may be provided)
I'm currently using a php script which grabs information from a API with curl (JSON format). I'm limited to a number of requests an hour so my plan was to read the file, insert the data into a mysql table so that I could re-read over and over again with no limitations. Then use a script to run every few hours to grab the data.
The script I created works however it's a bit buggy with regards to what it does if information is already in the table. If there isn't a previous entry then it inserts everything fine.
The JSON data is a multi depth array, and deals with images as well as data so for me, it's rather complex.
What I want the script to do is this. Each item is a property (letting agent website)
Check to see if the property exists in the database and the JSON. If there is no record in the database, then insert in. If there is a record in the database, update that record. If there is a property in the database which isn't in the JSON file, then delete it from the database.
This is basically the same plan for each sub array (pictures, floorplans, etc) however the images are copied from the url given (hosted on amazon) to my own host in order to speed up loading times, etc.
i've added a copy of the code but obviously its going to be stupidly hard to understand.
Is there any way this could be split into different functions to try and sort it out? haha

I have only today started looking at this and am used to: Code: [Select] <?php $con = mysql_connect();//etc mysql_close($connection); ?> Am I right that with mysqli (OO) that I don't need to set a connection variable wither when connecting or closing?? Code: [Select] <?php mysqli::connect();//etc mysqli::close(); ?> What about with multiple databases, does mysqli keep track for me, as I am used to this: Code: [Select] <?php $con1 = mysql_connect();//db1 $con2 = mysql_connect();//db2 ?> //etc

Hello everyone, For two weeks now, I'm trying to get this database connection in my query. Can someone give me a solution and tell me what I've done wrong? Am I overlooking something? <?php class Mysql{ public function connect(){ $mysqli = new mysqli('localhost','root','','login'); } } class Query extends Mysql{ public function runQuery(){ $this->result = parent::connect()->query("select bla bla from bla bla"); } } $query = new Query; $query->runQuery(); ?> I have just started using MySQLi and am clueless it is giving me the follow errors in which i do not understand
Warning: mysqli_select_db() expects exactly 2 parameters, 1 given in C:\xampp\htdocs\Login\connect.php on line 23 Notice: Trying to get property of non-object in C:\xampp\htdocs\Login\connect.php on line 25 Notice: Use of undefined constant mysqli - assumed 'mysqli' in C:\xampp\htdocs\Login\connect.php on line 32 Warning: mysqli_query() expects parameter 1 to be mysqli, string given in C:\xampp\htdocs\Login\connect.php on line 32 Warning: mysql_fetch_assoc() expects parameter 1 to be resource, null given in C:\xampp\htdocs\Login\connect.php on line 33 can someone please explain to me why i am getting these? and my code is
$mysqli_db = mysqli_select_db("$db_name");
if($mysqli_db->connect_errno) {
printf("Database not found: %s\n", $mysql->connect_error);
exit();
}
$sql = "SELECT * FROM $tbl_name WHERE username='$username' AND password='$password'";
$result = mysqli_query($sql);
$row = mysqli_fetch_assoc($result);
I just got rid off most the errors the only ones left are

Edited by Tom8001, 30 November 2014 - 12:43 PM. When running the following code i get the error: Call to undefined method mysqli::errno() the code: $conn = new mysqli(HOST, USER, PASSWORD, DATABASE); if ($conn->errno() !== 0) { $msg = $conn->error(); throw new connErrorException($msg, 'Connect'); } I am fairly new to classes but as i understand it this should be correct. I am using mysql 5.1 so mysqli is on by default. I have even checked the php ini and everything looks fine there in respect to this. Any advice? I dont know whether the statement is correct.....i just tried it.....and it didn't work. $stmt->bind_param('ssiiiss',$_POST['name'],$_POST['email'],$_POST['d'],$_POST['m'],$_POST['y'],$_POST['add'],$_POST['phone']); here my first two values are strings and next 2 tiny int's next is int and last 2 again strings.

Ok I am trying to use mysqli instead of the usual mysql. Mysql would be outdated. With mysqli, sgl-injection is impossible if you use the "?" in those codes. I would normally use a function but I've made a simple script to find the error. I use $parameters and $sql because these are the data I need to give as parameters to the function, so I used it here too but without the function actually. Code: [Select] ini_set('display_errors',1); // 1 == aan , 0 == uit error_reporting(E_ALL | E_STRICT); # sql debug define('DEBUG_MODE',true); // true == aan, false == uit $userid = 11; $lang = 1; $newLink = "testing123"; $db_host = "localhost"; $db_gebruiker = "root"; $db_wachtwoord = ''; $db_naam = "projecteasywebsite"; $sql= "INSERT tbl_link(userid,linkcat,linksubid,linklang,linkactive,linktitle) VALUES(?, ?, ?, ?, ?, ?)"; $parameters = '"iiisis", $userid, 1, 0, $lang, 1, $newLink'; echo $parameters; $mysqli = new mysqli($db_host, $db_gebruiker, $db_wachtwoord, $db_naam); $stmt = $mysqli->prepare($sql); $stmt->bind_param($parameters); $stmt->execute(); echo "<br><br>". mysqli_connect_errno(); echo "<br><br>". mysqli_report(MYSQLI_REPORT_ERROR); $stmt->close(); $mysqli->close(); I got Wrong parameter count for mysqli_stmt::bind_param() So naturally a problem when we execute : Warning: mysqli_stmt::execute() [mysqli-stmt.execute]: (HY000/2031): No data supplied for parameters in prepared statement ($stmt->execute() Is someone using mysqli too ? Hi everyone,
I can’t understand what happens… When I try my site in WAMP, I have the follow errors: Deprecated: mysql_query(): The mysql extension is deprecated and will be removed in the futu use mysqli or PDO (…) Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in (…) The same happened with the connect to mysql, but I solved using mysqli extension. But in this case is totally diferente. When I use the mysqli_query or mysqli_num_rows that are the alternatives presented I receive again other error, in PHP Manual says: "function.mysqli-query doesn't exist. Closest matches:" Someone know solve this problem??? When I use MySQL

Im using Mysqli and im trying to limit the results by 10 and order them from last to first from the database.
$sqlhorses = "SELECT Place FROM `*` WHERE `Horse` ='".$db->real_escape_string($row['horse']). "'";the above works but when i added the limit 6 to the end it shows errors. Can anyone help?

I am not certain why the following code works: Code: [Select] ... $sqlCmd = "select * from usrdata"; $rs = $mysqli->query($sqlCmd); ... and the following code gives me a 500 internal error: Code: [Select] ... $sqlCmd = "select * from usrdata"; $result= dbQuery($sqlCmd); ... function dbQuery($sqlCmd){ $rt = array(); $rs = $mysqli->query($sqlCmd); while($row = $rs->fetch_assoc ()){ $rt[] = $row; } return 'records: ' . json_encode($rt); } The error occurs on the mysqli->query. Thanks for any help. Cheers! I have converted my mysql to mysqli and am working on converting some functions. My question - Can I not just convert the mysql to mysqli? This is the full code: Code: [Select] class zipcode_class { var $last_error = ""; // last error message set by this class var $last_time = 0; // last function execution time (debug info) var $units = _UNIT_MILES; // miles or kilometers var $decimals = 2; // decimal places for returned distance function get_zip_point($zip) { // This function pulls just the lattitude and longitude from the // database for a given zip code. $sql = "SELECT lat, lon from zip_code WHERE zip_code='$zip'"; $r = $mysqli->query($sql); if (!$r) { $this->last_error = mysql_error(); return false; } else { $row = mysql_fetch_array($r); mysql_free_result($r); return $row; } } function calculate_mileage($lat1, $lat2, $lon1, $lon2) { // used internally, this function actually performs that calculation to // determine the mileage between 2 points defined by lattitude and // longitude coordinates. This calculation is based on the code found // at http://www.cryptnet.net/fsp/zipdy/ // Convert lattitude/longitude (degrees) to radians for calculations $lat1 = deg2rad($lat1); $lon1 = deg2rad($lon1); $lat2 = deg2rad($lat2); $lon2 = deg2rad($lon2); // Find the deltas $delta_lat = $lat2 - $lat1; $delta_lon = $lon2 - $lon1; // Find the Great Circle distance $temp = pow(sin($delta_lat/2.0),2) + cos($lat1) * cos($lat2) * pow(sin($delta_lon/2.0),2); $distance = 3956 * 2 * atan2(sqrt($temp),sqrt(1-$temp)); return $distance; } function get_zips_in_range($zip, $range, $sort=1, $include_base) { // returns an array of the zip codes within $range of $zip. Returns // an array with keys as zip codes and values as the distance from // the zipcode defined in $zip. $this->chronometer(); // start the clock $details = $this->get_zip_point($zip); // base zip details if ($details == false) return false; // This portion of the routine calculates the minimum and maximum lat and // long within a given range. This portion of the code was written // by Jeff Bearer (http://www.jeffbearer.com). This significanly decreases // the time it takes to execute a query. My demo took 3.2 seconds in // v1.0.0 and now executes in 0.4 seconds! Greate job Jeff! // Find Max - Min Lat / Long for Radius and zero point and query // only zips in that range. $lat_range = $range/69.172; $lon_range = abs($range/(cos($details[0]) * 69.172)); $min_lat = number_format($details[0] - $lat_range, "4", ".", ""); $max_lat = number_format($details[0] + $lat_range, "4", ".", ""); $min_lon = number_format($details[1] - $lon_range, "4", ".", ""); $max_lon = number_format($details[1] + $lon_range, "4", ".", ""); $return = array(); // declared here for scope $sql = "SELECT zip_code, lat, lon FROM zip_code "; if (!$include_base) $sql .= "WHERE zip_code <> '$zip' AND "; else $sql .= "WHERE "; $sql .= "lat BETWEEN '$min_lat' AND '$max_lat' AND lon BETWEEN '$min_lon' AND '$max_lon'"; $r = mysql_query($sql); if (!$r) { // sql error $this->last_error = mysql_error(); return false; } else { while ($row = mysql_fetch_row($r)) { // loop through all 40 some thousand zip codes and determine whether // or not it's within the specified range. $dist = $this->calculate_mileage($details[0],$row[1],$details[1],$row[2]); if ($this->units == _UNIT_KILOMETERS) $dist = $dist * _M2KM_FACTOR; if ($dist <= $range) { $return[str_pad($row[0], 5, "0", STR_PAD_LEFT)] = round($dist, $this->decimals); } } mysql_free_result($r); } // sort array switch($sort) { case _ZIPS_SORT_BY_DISTANCE_ASC: asort($return); break; case _ZIPS_SORT_BY_DISTANCE_DESC: arsort($return); break; case _ZIPS_SORT_BY_ZIP_ASC: ksort($return); break; case _ZIPS_SORT_BY_ZIP_DESC: krsort($return); break; } $this->last_time = $this->chronometer(); if (empty($return)) return false; return $return; } } Hey. I was writing my class object for a database connection and while I was writing the query part, I came to wonder whether I should use mysql_real_escape_string or mysqli_real_escape_string to make the query mysql friendly, what's the difference? I am updating some old code to the IMPROVED version of PHP and running into a problem in this section after connecting successfully to my database:
// retrieve the record that was selected
$record_id = (isset($_POST['record_id'])) ? $_POST['record_id'] : '';
//check for $record_id emptiness
if(!empty($record_id)){
// Retrieve ALL the data from the "example" table
$result = mysqli_query($conn, "SELECT * FROM $table WHERE id = $record_id ")
or die(mysqli_error());
// store the record of the "example" table into $row
$row = mysqli_fetch_array( $result, MYSQLI_BOTH );
}
Not sure what I'm missing or what needs to be re-organized. Please advise. Hi, I am having problems returning values from a select statement. When I query directly in the databse, I get back the information I am looking for. I use an includes file for the database connection and my page shows that the connection was successful. Here is my code: Code: [Select] <?php $search = $_GET['searchFor']; $words = explode(" ", $search); $phrase = implode("%' AND articlename LIKE '%", $words); $sql ="SELECT * FROM articles WHERE articlename LIKE '%phrase%'"; $result =$conn->query($sql) or die('Sorry, could not get any articles at this time'); $row =($result->fetch_all()) or die('No records found'); $numRows =$result->num_rows; If($numRows==0) { echo "<h2>Sorry, no articles were found with '$search' in them.</h2>"; } else { While($row=$result->fetch_assoc()) { $articleid = $row['articleid']; $title = $row['articlename']; $shortdesc = $row['shortdesc']; echo "<h2>Search Results</h2><br><br>\n"; echo "<a href=\"index.php?content=showarticle&id=$articleid\">$title</a><br>\n"; echo "$shortdesc<br><br>\n"; } } ?> The search term is coming from a search form in the navigation. I have used "echo" statements to check and make sure that the sesrch word is coming through to tghe page containing the above code. I have tried mysqli_error() statements in several places and don't see where the problem is. When I try the search the message that comes back is "No records found" Does not makee sense because I know it is there, can find it, and even have the same syntax as the SELECT statement I use when I ask for the php code. Going crazy trying to sort this out. Any suggestions, help etc are greatly appreciated. Thank youi. |
