我有几个需要插入数据库的大表格。

我目前正在这样做

$stmt = $memberMysqli->prepare("INSERT INTO questionnairebespokeexerciseplan(userid,date,naturalbodytype,framesizewrist,framesizeelbow,fitnessgoals,workpattern,sleephours,runningbarriers,workcommute,workdistance,smoke,biomechanicalissues,limitingillness,reletivesheartproblems,birthlast12months,recurringinjuries,regularmedication,pregnant,anythingelsehealth,gymmember,runoutdoors,wouldyouliketorunoutdoors,homeequipments,whattypeequipment,exercisetime,heartratemonitor,restingheartrate,actualheartrate,maxheartrate,heartratesteadyrun,heartratebreathless,trainingshoes,preferredexercisetype,exerciseclasses,classdays,bike,bikemodel,runlunchtimebeforework,clubmember,clubschedule,personaltraining,otherheartrate,foottype) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");

$stmt->bind_param('ssssssssssssssssssssssssssssssssssssssssssss',
                                                $_POST['userid'],
                                        $date,
                                        $_POST['naturalbodytype'],
                                        $_POST['framesizewrist'],
                                        $_POST['framesizeelbow'],
                                        $_POST['fitnessgoals'],
                                        $_POST['workpattern'],
                                        $_POST['sleep'],
                                        $_POST['runbarriers'],
                                        $_POST['workcommute'],

                                        $_POST['illnesses'],
                                        $_POST['heartcondition'],
                                        $_POST['givenbirth'],
                                        $_POST['injuries'],
                                        $_POST['medication'],
                                        $_POST['pregnant'],
                                        $_POST['anythingelse'],
                                        $_POST['gymmember'],
                                        $_POST['runoutdoors'],
                                        $_POST['liketorunoutside'],
                                        $_POST['homeequipment'],
                                        $_POST['equipment'],
                                        $_POST['besttime'],
                                        $_POST['heartratemonitor'],
                                        $_POST['restingheartrate'],
                                        $_POST['actualheartrate'],
                                        $_POST['actualmaxheartrate'],
                                        $_POST['heartratesteadyrun'],
                                        $_POST['heartratebreathless'],
                                        $_POST['trainingshoes'],
                                        $_POST['preferredexersize'],
                                        $_POST['classes'],
                                        $_POST['classdays'],
                                        $_POST['bike'],
                                        $_POST['whatbike'],
                                        $_POST['beforeworklunchtime'],
                                        $_POST['clubmember'],
                                        $_POST['clubschedule'],
                                        $_POST['personaltrainer'],
                                        $_POST['otherheartrate'],
                                        $_POST['foottype']
                                        );

我只是在想是否有更好/更快的方法来做到这一点？

目前，创建它需要一些时间，当事情不正确时对其进行调试同样耗时。

您可以自己编写一个脚本来自动生成此语句。确保您保持字段名称一致（在您的表单和数据库中），然后也许这样的一段代码可以为您工作：

// ADD ALL YOUR FIELDS TO THIS ARRAY. 
// THIS SHOULD BE THE ONLY PART OF THE CODE 
// WHICH YOU WILL HAVE TO MAINTAIN.

$fields = array(
'userid',
'date',
'naturalbodytype',
'framesizewrist' //etc. add all your fields
);

//you may have to adjust some fields manually:

$_POST['date'] = $date;


//HERE IS WHERE THE AUTOMATED PART STARTS
//YOU WONT EVER HAVE TO TOUCH THIS PART

//writing all fields for the query
$all_fields = implode(', ' $fields); 

//writing the correct number of questionmarks    
$questionmarks = str_repeat('?, ' count($fields)-1).'?';

//generate your statement
$stmt = $memberMysqli->prepare(
"INSERT INTO questionnairebespokeexerciseplan
 ( {$all_fields} ) 
 VALUES 
 ( {$questionmarks} )");

//write the correct amount of 's' characters for parameter types
$parameter_types = str_repeat('s' count($fields));


//generate the code which will write the parameters

$all_fields_to_bind=array();

foreach($fields as $field)
{
    $all_fields_to_bind[] = "\$_POST['". $field. "']";
}

//generate the code to be evaluated
$eval_statement = '$stmt->bind_param($parameter_types,'.implode(', ', $all_fields_to_bind).');';

//evaluate (meaning execute) your dynamically generated code
eval($eval_statement);

我没有对此进行测试，可能仍然存在一些语法错误。我也不知道它有多安全！但它应该可以工作，因为我在 SELECT 语句中使用了类似的东西。

SafeMysql可以让你的代码缩短 3 倍。尽管列出所有允许的字段是必不可少的。

$allowed = explode(",","userid,date,naturalbodytype,framesizewrist,framesizeelbow,fitnessgoals,workpattern,sleephours,runningbarriers,workcommute,workdistance,smoke,biomechanicalissues,limitingillness,reletivesheartproblems,birthlast12months,recurringinjuries,regularmedication,pregnant,anythingelsehealth,gymmember,runoutdoors,wouldyouliketorunoutdoors,homeequipments,whattypeequipment,exercisetime,heartratemonitor,restingheartrate,actualheartrate,maxheartrate,heartratesteadyrun,heartratebreathless,trainingshoes,preferredexercisetype,exerciseclasses,classdays,bike,bikemodel,runlunchtimebeforework,clubmember,clubschedule,personaltraining,otherheartrate,foottype");

$data = $db->filterArray($_POST,$allowed);
$sql = "INSERT INTO questionnairebespokeexerciseplan SET ?u";
$db->query($sql, $data);
