json_encode和highcharts [英] json_encode and highcharts
问题描述
我正在尝试使用jQuery(特别是Highcharts库)在PHP和MySQL中创建图形，我设法使用MySQL数据库中的数据制作了图表，但是如果这些数据在数据库中，则这些数据显示了一些数据，但没有显示其他数据. ，例如，产生10个结果5的查询是好的，但其他5个则不行，我已经在网络上进行了一些研究，并且我了解这是由于我通过json_encode在MySQL中传递查询结果而导致的问题，我希望你们中的一些人可以告诉我，因为我有此错误，或者如果我滥用JSON，非常感谢. 代码: index.php
I'm trying to make graphs in PHP and MySQL using jQuery, specifically with Highcharts library, I have managed to make the chart with data from MySQL database, but these data show some data if they are in the databases but not others, for example, a query that yields 10 results 5 are good, but the other five did not, I have done some research on the web and I understand it is due to a problem when I pass the result of my query in MySQL by json_encode, I hope some of you can tell me because I have this error or if I'm misusing the JSON, thank you very much. Code: index.php

<?php

$result = mysql_query("SELECT
clientes.cliente,
COUNT(incidencias.idIncidencia) AS nIncidencias
FROM incidencias
INNER JOIN clientes ON incidencias.idCliente = clientes.idCliente
GROUP BY incidencias.idCliente
ORDER BY nIncidencias DESC
LIMIT 0,10");
$rows = array();
while($r = mysql_fetch_array($result))
{
$row[0] = $r[0];
$row[1] = $r[1];
array_push($rows,$row);
}
//print json_encode($rows, JSON_PRETTY_PRINT);
echo json_encode($rows, JSON_NUMERIC_CHECK | JSON_PRETTY_PRINT);
mysql_close($con);
?>
例如，该错误是当我想在图表中显示数据库的10行时，它向我显示此表单的结果:
The error is for example when I want to show 10 row of the database in the graph, it show me the results of this form:
1st. row-> show me "slice"
2nd. row-> the registerok,
3th. row-> show me "slice"
4. row-> the registerok,
5. row-> the registerok,
6.row-> show me "slice"
7.row->the registerok,
8.row-> show me "slice"
9.row->the registerok,
10.row-> show me "slice"
问题在于，图表(pie)中显示的是正确数据，而其他数据则未显示，就好像某些记录或tubiese跳过了5个注册限制，不是我不知道我错了哪里. :(
The problem is that in the graph (pie) displays correct data but not others, it is as if some records or tubiese skipped a limit of 5 registrros, not I do not know where I'm wrong. :(
感谢您的帮助:)
推荐答案
首先，我将尝试为数组元素赋予一个值，而不是使用索引.给您的阵列键起一个名字.还要从编码中删除所有大写字母.我正在使用ipad，无法编写代码，但是如果您有任何疑问，请告诉我.
First of all I would try to give the array elements a value, instead of using the index. Give your array key a name. As well remove all the uppercase letters from your encode. I am on an ipad and unable to code, but let me know if you have questions.
