如何将多条记录添加到我的数据库

Question

一直在处理表格。我想将表单中的信息添加到数据库中，这样我就可以在网站上其他地方的日历中显示它。

我在网上找到了一些其他代码，但仅适用于 1 个值。并且由于某种原因只有 1 次。 现在有了这个（顺便说一句在wordpress中工作）

function elh_insert_into_db() {

global $wpdb;
// creates my_table in database if not exists
$table = $wpdb->prefix . "table_form"; 
$charset_collate = $wpdb->get_charset_collate();
$sql = "CREATE TABLE IF NOT EXISTS $table (
    `id` mediumint(9) NOT NULL AUTO_INCREMENT,
    `name` text NOT NULL,
    `email` text NOT NULL,
    `date` text NOT NULL,
    `starttijd` text NOT NULL,
    `eindtijd` text NOT NULL,
    `opmerkingen` text NOT NULL,
UNIQUE (`id`)
) $charset_collate;";
require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
dbDelta( $sql );
// starts output buffering
ob_start();
?>
<form action="#v_form" method="post" id="v_form">
    <label for="visitor_name"><h3>Naam:</h3></label>
        <input type="text" name="visitor_name" id="visitor_name" />

<label for="visitor_email"><h3>E-mail:</h3></label>
    <input type="email" name="visitor_email" id="visitor_email" />

<label for="visitor_date"><h3>Datum:</h3></label>
    <input type="date"  name="visitor_date" id="visitor_date" />

<label for="visitor_start_time"><h3>Starttijd:</h3></label>
    <input type="time"  name="visitor_start_time" id="visitor_start_time" />

<label for="visitor_end_time"><h3>Eindtijd:</h3></label>
    <input type="time"  name="visitor_end_time" id="visitor_end_time" />

    <label for="visitor_text"><h3>Opmerkingen:</h3></label>
        <input type="text" name="visitor_text" id="visitor_text" />

    <input type="submit" name="submit_form" value="Aanvragen" />
</form>
<?php
$html = ob_get_clean();
// does the inserting, in case the form is filled and submitted
if ( isset( $_POST["submit_form"] ) && $_POST["visitor_name"] != "" ) {
$table = $wpdb->prefix."table_form";
$name = strip_tags($_POST["visitor_name"], "");
$wpdb->insert( 
    $table, 
    array( 
        'name' => $name
    )
);


    $html = "<p>check this is inserted in the database <strong>$name, $email, $date , $starttijd, 
$eindtijd, $opmerkingen</strong> what a succes!</p>";
}
// if the form is submitted but the name is empty
if ( isset( $_POST["submit_form"] ) && $_POST["visitor_name"] == "" )
    $html .= "<p>You need to fill the required fields.</p>";
// outputs everything
return $html;

}
// adds a shortcode you can use: [insert-into-db]
add_shortcode('elh-db-insert', 'elh_insert_into_db');

Answer 1

您只需处理/插入名称（形成您的代码）：

$name = strip_tags($_POST["visitor_name"], "");    
$wpdb->insert( 
    $table, 
    array( 
        'name' => $name
    )
)

修改这部分代码以添加其他信息。您的 $_POST 中的每个项目都需要处理。
