我有这个脚本，它接受一个变量并将其放入表中。我的connect.php文件是正确的，并选择了正确的数据库，但由于某种原因，这些数据不会插入。它说它成功但没有任何东西放在桌子上
我的剧本
if(!empty($_POST['phrase'])){
$phrase = $_POST['phrase'];
$phrase = mysql_real_escape_string($phrase);
$phrase = preg_replace("/[^A-Za-z ]/", "", $phrase);
$query5 = mysql_query('SELECT phrase FROM dictionary WHERE phrase = "'.$phrase.'" '); // Check the database
if(mysql_num_rows($query5)>0){
null;
}else{
echo $phrase;
$query10 = "INSERT into dictionary(adjective, noun, phrase, subject, verb) values(NULL, NULL, '$phrase', NULL, NULL)";
$result = mysqli_query($query10);
echo "<pre>Debug: $query10</pre>\m";
//$result = mysqli_query($con, $query);
if ( false===$result ) {
printf("error: %s\n");
}
else {
echo 'done.';
}
mysqli_close();
}
//Debugging Purpose
echo '<span class="error" > -'. $phrase .'</span>';
}
回声完成了。但表格没有更新
这是我的表格设置方式

--
CREATE DATABASE IF NOT EXISTS `dictionary` DEFAULT CHARACTER SET latin1 COLLATE latin1_swedish_ci;
USE `dictionary`;

答案 0 :(得分：-1)
mysql_*与mysqli_* API混合使用。 mysql_*已经deprecated，我建议你改用prepared statement。让我们首先重新建立与MySQL数据库的连接：
$con = new mysqli("host", "username", "password", "dictionary"); /* REPLACE NECESSARY DATA INSIDE */
/* CHECK CONNECTION */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
然后检查表单中的每个POST数据：
if(!empty($_POST["phrase"])){ /* IF SUBMITTED phrase DATA IS NOT EMPTY */
/* LETS CHECK FIRST IF THE PASSED ON phrase DATA ALREADY EXIST IN THE phrase TABLE */
if($stmt = $con->prepare("SELECT * FROM phrase WHERE phrase = ?")){
$stmt->bind_param("s", $_POST["phrase"]); /* BIND THE PASSED ON DATA TO THE QUERY */
$stmt->execute(); /* EXECUTE THE QUERY */
$stmt->store_result(); /* STORE THE RESULT */
$noofphrase = $stmt->num_rows; /* GET THE NUMBER OF RESULTS OF THE EXECUTE QUERY */
if($noofphrase ==0){ /* IF phrase IS NOT YET IN THE phrase TABLE */
$stmt2 = $con->prepare("INSERT INTO phrase (phrase) VALUES (?)"); /* START INSERT QUERY */
$stmt2->bind_param("s", $_POST["phrase"]); /* BIND THE PASSED ON DATA TO THE QUERY */
$stmt2->execute(); /* EXECUTE THE INSERT QUERY */
$stmt2->close(); /* CLOSE THE INSERT QUERY PREPARED STATEMENT */
}
$stmt->close(); /* CLOSE THE PREPARED STATEMENT */
} /* END OF PREPARED STATEMENT */
} /* END OF IF phrase IS NOT EMPTY */
然后对adjective，noun，subject和verb重复此操作。
这是一项繁琐的工作。代码将看起来已填充。那么为什么我们不创建一个函数，它将参数化键入的数据，表名和列名。这是一种更好的方法，因为它们以相同的模式运行。
<?php
function CheckAndInsert ($data, $tablename, $columnname){
global $con;
if(!empty($data)){ /* CHECK IF KEYED-IN DATA IS NOT EMPTY */
/* LETS CHECK FIRST IF THE PASSED ON phrase DATA ALREADY EXIST IN THE phrase TABLE */
if($stmt = $con->prepare("SELECT * FROM ? WHERE ? = ?")){
$stmt->bind_param("sss", $tablename, $columnname, $data); /* BIND THE PASSED ON DATA TO THE QUERY */
$stmt->execute(); /* EXECUTE THE QUERY */
$stmt->store_result(); /* STORE THE RESULT */
$noofresult = $stmt->num_rows; /* GET THE NUMBER OF RESULTS OF THE EXECUTE QUERY */
if($noofresult ==0){ /* IF phrase IS NOT YET IN THE phrase TABLE */
$stmt2 = $con->prepare("INSERT INTO ? (?) VALUES (?)"); /* START INSERT QUERY */
$stmt2->bind_param("sss", $tablename, $columnname, $data); /* BIND THE PASSED ON DATA TO THE QUERY */
$stmt2->execute(); /* EXECUTE THE INSERT QUERY */
$stmt2->close(); /* CLOSE THE INSERT QUERY PREPARED STATEMENT */
} /* END OF CHECKING NO OF RESULTS FROM FIRST QUERY */
$stmt->close(); /* CLOSE THE PREPARED STATEMENT */
} /* END OF PREPARED STATEMENT */
} /* END OF CHECKING
} /* END OF FUNCTION */
?>
因此，当用户提交表单时，只需调用此函数。
CheckAndInsert($_POST["phrase"], "phrase", "phrase");
CheckAndInsert($_POST["adjective"], "adjective", "adjective");
CheckAndInsert($_POST["noun"], "noun", "noun");
CheckAndInsert($_POST["subject"], "subject", "verb");
CheckAndInsert($_POST["verb"], "subject", "verb");
