[英]Fetch data from two mysql tables and export to JSON
我需要以這種格式創建json數據:
{
"cols": [{
"label": "ID",
"type": "number"
}, {
"label": "Vrsta",
"type": "string"
}, {
"label": "Artikl",
"type": "string"
}, {
"label": "Neto kol",
"type": "number"
}, {
"label": "Bruto kol",
"type": "number"
}, {
"label": "Mera",
"type": "string"
}, {
"label": "Neto iznos",
"type": "number"
}, {
"label": "Bruto",
"type": "number"
}, {
"label": "Porez",
"type": "number"
}, {
"label": "Dobavljac",
"type": "string"
}, {
"label": "Datum",
"type": "date"
}, {
"label": "Skladiste",
"type": "string"
}, {
"label": "Valuta",
"type": "string"
}, {
"label": "Placeno",
"type": "string"
}, {
"label": "Nacin placanja",
"type": "string"
}, {
"label": "Placeni iznos",
"type": "number"
}, {
"label": "Opis",
"type": "string"
}],
"rows": [{
"c": [{
"v": 1
}, {
"v": "gorivo"
}, {
"v": "biodizel"
}, {
"v": 22
}, {
"v": 22
}, {
"v": "l"
}, {
"v": 29
}, {
"v": 36
}, {
"v": 20
}, {
"v": "Nis"
}, {
"v": "Date(2014, 02, 25)"
}, {
"v": "Bure 5"
}, {
"v": "e"
}, {
"v": "Da"
}, {
"v": "gotovinsko"
}, {
"v": 36
}, {
"v": "kupljeno gorivo za setvu"
}]
}, {
"c": [{
"v": 2
}, {
"v": "djubrivo"
}, {
"v": "b432"
}, {
"v": 5
}, {
"v": 5
}, {
"v": "m3"
}, {
"v": 100
}, {
"v": 120
}, {
"v": 20
}, {
"v": "STR polja"
}, {
"v": "Date(2014, 02, 25)"
}, {
"v": "dvoriste iza"
}, {
"v": "e"
}, {
"v": "da"
}, {
"v": "kompenzacija"
}, {
"v": 120
}, {
"v": "Djubrenje"
}]
}]
}
但是我用一個表用此代碼來做到這一點:
try {
/* Establish the database connection */
$conn = new PDO("mysql:host=localhost;dbname=$dbname", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
/* select all the weekly tasks from the table googlechart */
$result = $conn->query('SELECT * FROM zalihe');
$rows = array();
$table = array();
$table['cols'] = array(
array('label' => 'ID', 'type' => 'number'),
array('label' => 'Vrsta', 'type' => 'string'),
array('label' => 'Artikl', 'type' => 'string'),
array('label' => 'Neto kol', 'type' => 'number'),
array('label' => 'Bruto kol', 'type' => 'number'),
array('label' => 'Mera', 'type' => 'string'),
array('label' => 'Neto iznos', 'type' => 'number'),
array('label' => 'Bruto', 'type' => 'number'),
array('label' => 'Porez', 'type' => 'number'),
array('label' => 'Dobavljac', 'type' => 'string'),
array('label' => 'Datum', 'type' => 'date'),
array('label' => 'Skladiste', 'type' => 'string'),
array('label' => 'Valuta', 'type' => 'string'),
array('label' => 'Placeno', 'type' => 'string'),
array('label' => 'Nacin placanja', 'type' => 'string'),
array('label' => 'Placeni iznos', 'type' => 'number'),
array('label' => 'Opis', 'type' => 'string')
);
/* Extract the information from $result */
foreach($result as $r) {
$temp = array();
// the following line will be used to slice the Pie chart
$temp[] = array('v' => (int) $r['ID']);
$temp[] = array('v' => (string) $r['vrsta']);
$temp[] = array('v' => (string) $r['artikl']);
$temp[] = array('v' => (int) $r['neto_kol']);
$temp[] = array('v' => (int) $r['bruto_kol']);
$temp[] = array('v' => (string) $r['jmere']);
$temp[] = array('v' => (int) $r['neto_iznos']);
$temp[] = array('v' => (int) $r['bruto_iznos']);
$temp[] = array('v' => (int) $r['porez']);
$temp[] = array('v' => (string) $r['dobavljac']);
$temp[] = array('v' => 'Date('.str_replace('-',', ',($r['datum'])).')');
$temp[] = array('v' => (string) $r['skladiste']);
$temp[] = array('v' => (string) $r['valuta']);
$temp[] = array('v' => (string) $r['placeno']);
$temp[] = array('v' => (string) $r['nacin_placanja']);
$temp[] = array('v' => (int) $r['placeni_iznos']);
$temp[] = array('v' => (string) $r['opis']);
// Values of each slice
$rows[] = array('c' => $temp);
}
$table['rows'] = $rows;
// convert data into JSON format
$jsonTable = json_encode($table);
//echo $jsonTable;
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
echo $jsonTable;
現在,我還有另外一張表,我也需要從該表中獲取數據並放入相同的json文件中:
該表是:
CREATE TABLE IF NOT EXISTS `skladista` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`naziv` text NOT NULL,
`kapacitet` int(11) NOT NULL,
`jmere` text NOT NULL,
`vlasnistvo` text NOT NULL,
`beleske` text NOT NULL,
PRIMARY KEY (`ID`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
現在,我如何將第二個表"skladista"
中的數據添加到php文件中,並使用兩個mysql表創建一個php-JSON文件...
我將輕松添加“ cols”,因為它只是“字符串名稱”,但隨后我需要從第二個表中獲取數據...
那么如何:mysql表“ zalihe” +“ skladista” =一個json文件?
請幫忙!
可能這個小例子會對您有所幫助。
// Get the max key of your already existed $temp array
$max_key_val = max(array_keys($temp));
// Fetch data from table-skladista
$data = mysql_query("Your-SQL-query");
while($row = mysql_fetch_array($data))
{
$temp[$max_key_val++] = array('v' => $row['tbl_col_name']);
}
// Then follow your same procedure
$rows[] = array('c' => $temp);
$table['rows'] = $rows;
$jsonTable = json_encode($table);
