Question

我正在使用php和MySQL。当我提交表单数据时，数据表中没有存储＆＃39; plantation_journal_nursery_details＆＃39;。我被困在这里。任何人都可以建议我，我该如何解决这个问题？先谢谢你们。代码如下：

create_journal.php

<form action="data_fetch.php" action="post">

Frontend Table

Backend Table

Answer 1

在编辑问题之前，您的插入查询包含...

...VALUES ('$plantation_journal_no',$configurarion','$slope','$water_table_in_...

请注意，您的单引号不匹配。你应该

...VALUES ('$plantation_journal_no','$configurarion','$slope','$water_table_in_...

如果您在查询中检查过错误，则会立即发现此问题。像这样的代码会有所帮助。

if($result){
    echo "<script>alert('data submitted.');</script>";
    header("Location:create_journal.php");
}
else {
    die  $mysqli->error;
}

专业提示：格式化代码，这样您就不必水平滚动查看整个查询。通过这种方式检查查询并发现错误要容易得多。您可以使用php's heredoc syntax for string constants来执行此操作。

这就是它的样子。

    $sql= <<<INSERTQUERY
INSERT INTO `plantation_journal_nursery_details`
       (`plantation_journal_no`, `location`, `area`, `type_of_nursery`, 
        `central_nursery_name`, `state_nursery_name`, `mother_bed_size`, 
        `quantity`, `source_of_seed`, `polypot_bed_size`, `quantity_p`, 
        `hycopot_bed_size`, `quantity_h`) 
  VALUES 
       ('$plantation_journal_no','$location','$area1','$type_of_nursery',
        '$central_nursery_name','$central_nursery_name','$mother_bed_size',
        '$quantity_m','$source_of_seed','$polypot_bed_size','$quantity_p',
        '$hycopot_bed_size','$quantity_h');
INSERTQUERY;

数据没有使用php mysql提交到数据库
