Body
I have a question about this code below. When I want to select one item (in this case street) everything works with no errors in debugging mode. (I'm using AJAX to generate a message) <pre><code>public function placeAvailable() { //open connectie naar database include("Connection.php"); $sSql= "select Street from tblPlaces where Street = '".$this->m_sStreet."'"; $vResult=$mysqli->query($sSql); if($vResult->num_rows>0) { return(false); } else { return(true); } $mysqli->close(); } </code></pre> When I want to add an extra parameter to my select query I got an error (Notice: Trying to get property of non-object in /Applications/MAMP/htdocs/foodsquare/assets/classes/places.class.php on line 86) <pre><code>$vResult=$mysqli->query($sSql); if($vResult->num_rows>0) </code></pre> The extra parameter I add is the folowing. <pre><code>$sSql= "select Street from tblPlaces where Street = '".$this->m_sStreet."' AND where HouseNumber = '".$this->m_sHouseNumber."'"; </code></pre> Josh here you can see the whole code <pre><code><?php class Places { private $m_sName; private $m_sStreet; private $m_sHouseNumber; private $m_sCity; private $m_sCategory; public function __set($p_sProperty, $p_vValue) { switch($p_sProperty) { case "Name" : $this -> m_sName = $p_vValue; break; case "Street" : $this -> m_sStreet = $p_vValue; break; case "HouseNumber" : $this -> m_sHouseNumber= $p_vValue; break; case "City" : $this -> m_sCity = $p_vValue; break; case "Category" : $this -> m_sCategory = $p_vValue; break; } } public function __get($p_sProperty) { $vResult = null; switch($p_sProperty) { case "Name" : $vResult = $this -> m_sName; break; case "Street" : $vResult = $this -> m_sStreet; break; case "HouseNumber" : $vResult = $this -> m_sHouseNumber; break; case "City" : $vResult = $this -> m_sCity; break; case "Category" : $vResult = $this -> m_sCategory; break; } return $vResult; } public function addPlaces() { include_once("connection.php"); $sSql = "INSERT INTO tblPlaces (Name, Street, HouseNumber, City, Category) VALUES ('" . $mysqli -> real_escape_string($this -> m_sName) . "', '" . $mysqli -> real_escape_string($this -> m_sStreet) . "', '" . $mysqli -> real_escape_string($this -> m_sHouseNumber) . "', '" . $mysqli -> real_escape_string($this -> m_sCity) . "', '" . $mysqli -> real_escape_string($this -> m_sCategory) . "');"; if (!$mysqli -> query($sSql)) { throw new Exception("Er is iets mis gelopen bij het toevoegen van een plaats"); } } public function placeAvailable() { //open connectie naar database include("Connection.php"); global $mysqli; //sql query selecteert straat uit tblplaces waar de straat gelijk is aan het inputveld street uit het formulier $sSql= "select Street from tblPlaces where Street = '".$this->m_sStreet."' AND where HouseNumber = '".$this->m_sHouseNumber."'"; $vResult=$mysqli->query($sSql); if($vResult->num_rows>0) { //Street (place) is al in gebruik return(false); } else { //Hij is nog niet in gebruik return(true); } //database sluiten $mysqli->close(); } } ?> </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
