Php 数据未插入数据库

我有一个名为user_data_institutes的表，它的值被正确地传递，我已经调试过这些值被传递，并且没有传递空值

这是密码

$query = "INSERT INTO `secure_login`.`user_data_institution` (`id`, `namecontact`, `emailinst`, `nameofinst`, `yearsofexsistance`, `contactinst`, `institutionhour`, `websiteinst`, `address`, `institutionstate`, `institutioncity`, `institutionzipcode`, `aboutinst`, `institutiosizeoffaculty`, `institutionlearninglocatiom`, `nooflocations`, `learningaddress1`, `learninglocality1`, `learningaddress2`, `learninglocality2`, `learningaddress3`, `learninglocality3`, `learningaddress4`, `learninglocality4`, `learningaddress5`, `learninglocality5`, `coursename1`, `coursefeesinstitution1`, `frequencyoffeescollectioninstitution1`, `maxstudentsinstitution1`, `courselength1`, `courselength21`, `demoinstitution1`, `lengthofclassinstitution1`, `coursename2`, `coursefeesinstitution2`, `frequencyoffeescollectioninstitution2`, `maxstudentsinstitution2`, `courselength2`, `courselength22`, `demoinstitution2`, `lengthofclassinstitution2`, `coursename3`, `coursefeesinstitution3`, `frequencyoffeescollectioninstitution3`, `maxstudentsinstitution3`, `courselength3`, `courselength23`, `demoinstitution3`, `lengthofclassinstitution3`, `coursename4`, `coursefeesinstitution4`, `frequencyoffeescollectioninstitution4`, `maxstudentsinstitution4`, `courselength4`, `courselength24`, `demoinstitution4`, `lengthofclassinstitution4`, `coursename5`, `coursefeesinstitution5`, `frequencyoffeescollectioninstitution5`, `maxstudentsinstitution5`, `courselength5`, `courselength25`, `demoinstitution5`, `lengthofclassinstitution5`, `institutiondays1`, `institutiontime1`, `institutiondays2`, `institutiontime2`, `institutiondays3`, `institutiontime3`, `institutiondays4`, `institutiontime4`, `institutiondays5`, `institutiontime5`, `locationsforlearning1`, `locationsforlearning2`, `locationsforlearning3`, `locationsforlearning4`, `locationsforlearning5`) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";

$stmt = $mysqli->prepare($query);

$stmt->execute();

但是这个声明没有执行..请帮帮我

正在建立数据库连接，因为相同的文件包含正在执行的其他代码。

您的

bind_参数的语法不正确

您需要有一个字符来定义每个参数的数据类型，但不能在每个定义字母之间添加逗号

你是这样编码的

$stmt->bind_param('isss',$userid,$namecontact,$emailinst,$nameofinst);

为了简洁起见，我缩短了您的代码
RTFMs--您不需要在
$stmt->bind_-param（'I，s，s，s，s，s，s，…）中使用逗号。
只要
$stmt->bind_-param（'isssssss…
但是如上所述，RTM是第一个请不要在查询中查找最后一个查找错误的错误，非常感谢，先生..它现在工作得很好！顺便说一下，您添加了一个PDO标记；这不是PDO，是mysqli-我删除了它
