用于自动完成jQueryUI的MYSQL到JSON

MYSQL to JSON for Autocomplete jQueryUI

本文关键字:MYSQL JSON jQueryUI 用于      更新时间:2023-09-26

下面的代码显示了我正在做的事情。基本上,目的是从数据库中检索数据,并将其转换为jQueryUI的JSON格式。通过下面的方法和一个不使用array_to_json函数的方法,我能够返回json数据。例如:[{"name":"Kurt Schneider"},{"name":"Sam Tsui"}

但问题是,它仍然不能与自动完成一起工作。我用示例中提供的search.php替换了下面的代码,所以这显然是该代码的一个问题。

我开始时只有这个代码:

<?php
    include 'connect.php';
    mysql_select_db("database", $con);
    $search = mysql_query("SELECT name FROM artist");
    $rows = array();
    while($row = mysql_fetch_assoc($search)) {
        $result[] = $row;
    }
print json_encode($result);
?>

它实际上实现了与以下代码相同的结果(除了间距上的一些差异):(array_to_json函数是直接从示例中复制的)。

<?php
    include 'connect.php';
    mysql_select_db("database", $con);
    $search = mysql_query("SELECT name FROM artist");
    $rows = array();
    while($row = mysql_fetch_assoc($search)) {
        $result[] = $row;
    }
    function array_to_json( $array ){
    if( !is_array( $array ) ){
        return false;
    }
    $associative = count( array_diff( array_keys($array), array_keys( array_keys( $array )) ));
    if( $associative ){
        $construct = array();
        foreach( $array as $key => $value ){
            // We first copy each key/value pair into a staging array,
            // formatting each key and value properly as we go.
            // Format the key:
            if( is_numeric($key) ){
                $key = "key_$key";
            }
            $key = "'"".addslashes($key)."'"";
            // Format the value:
            if( is_array( $value )){
                $value = array_to_json( $value );
            } else if( !is_numeric( $value ) || is_string( $value ) ){
                $value = "'"".addslashes($value)."'"";
            }
            // Add to staging array:
            $construct[] = "$key: $value";
        }
        // Then we collapse the staging array into the JSON form:
        $result = "{ " . implode( ", ", $construct ) . " }";
    } else { // If the array is a vector (not associative):
        $construct = array();
        foreach( $array as $value ){
            // Format the value:
            if( is_array( $value )){
                $value = array_to_json( $value );
            } else if( !is_numeric( $value ) || is_string( $value ) ){
                $value = "'".addslashes($value)."'";
            }
            // Add to staging array:
            $construct[] = $value;
        }
        // Then we collapse the staging array into the JSON form:
        $result = "[ " . implode( ", ", $construct ) . " ]";
    }
    return $result;
}
    echo array_to_json($result);
?>
<?php
    include 'connect.php';
    mysql_select_db("database", $con);
    $search = mysql_query("SELECT name FROM artist");
    $rows = array();
    while($row = mysql_fetch_assoc($search)) {
        //don't add the array, just the name.
        $result[] = $row["name"];
    }
print json_encode($result);
?>

上面的代码应该返回JSON

["Kurt Schneider", "Sam Tsui", "Christina Grimmie"]
