php - 如何使用 PHP 从 MYSQL 检索值到单选按钮？

Question

我有自定义页面模板。在此模板中，有一个 html 表格，每个表格行中都带有单选按钮。我尝试从 MYSQl 检索单选按钮的值，但没有成功。

场景:如果用户选择"is"选项，则表行将被禁用。现在，单选按钮的值是检索的，但不是禁用"is"选项的功能。

如何解决这个问题？

PHP 已更新

        if (isset($_POST['list_location']) && $_POST['list_location'] != 'Select by Location'){
    $list_location = $_POST['list_location'];
    $result_location = $wpdb->get_results($wpdb->prepare("SELECT DISTINCT id, submit_time, last_name, first_name, middle_name, mobile_number, email, location, position, message, attachment_resume_id, process_resume FROM resume_databank WHERE location = '" . $list_location . "' ORDER BY location ASC", OBJECT));

        echo '<table>';
        echo '<tr>';
        $optionId = 0;
        echo '<th>Submit Time</th>';
        echo '<th>Last Name</th>';
        echo '<th>First Name</th>';
        echo '<th>Middle Name</th>';
        echo '<th>Mobile Number</th>';
        echo '<th>Email</th>';
        echo '<th>Location</th>';
        echo '<th>Position</th>';
        echo '<th>Message</th>';
        echo '<th>Resume</th>';
        echo '<th>Processed?</th>';
    for ($i=0;$i < count($result_location); $i++){
        $row = $result_location[$i];
        $optionId = $result_location[$i]->id;
        $checkYes   = "";
        $checkNo    = "";

        if($result_location[$i]->process_resume == "Yes"){
            $checkYes = "checked";
        }
        if($result_location[$i]->process_resume == "No"){
            $checkNo = "checked"; 
        }

    echo '<tr>';
        echo '<td id="submit_time">' . $result_location[$i]->submit_time . '</td>';
        echo '<td id="last_name">' . $result_location[$i]->last_name . '</td>';
        echo '<td id="first_name">' . $result_location[$i]->first_name . '</td>';
        echo '<td id="middle_name">' . $result_location[$i]->middle_name . '</td>';
        echo '<td id="mobile_number">' . $result_location[$i]->mobile_number . '</td>';
        echo '<td id="email">' . $result_location[$i]->email . '</td>';
        echo '<td id="location">' . $result_location[$i]->location . '</td>';
        echo '<td id="position">' . $result_location[$i]->position . '</td>';
        echo '<td id="message">' . $result_location[$i]->message . '</td>';
        echo '<td id="resumeFile'.$optionId.'"><a href=' . wp_get_attachment_url($result_location[$i]->attachment_resume_id) . '>Download Resume</a></td>';
        echo '<td id="radioOption><label for="Yes">Yes</label>
            <input type="radio" id="processedOptionYes'.$optionId.'" name="processedOption'.$optionId.'" ' . $checkYes . ' value="Yes" onclick="proccessedCheck('.$optionId.',\'Yes\')"/>
            <label for="No">No</label>
            <input type="radio" id="processedOptionNo'.$optionId.'" name="processedOption'.$optionId.'" ' . $checkNo . ' value="No" onclick="proccessedCheck('.$optionId.',\'No\')"/></td>';
    echo '</tr>';
    }
    echo '</table>';
}

JS:

function proccessedCheck(optionId,optionAnswer){
    if(optionAnswer == 'Yes'){
        if (confirm('You have chosen ' + optionAnswer + ', is this correct?')){
            jQuery("#processedOptionYes" + optionId).attr('disabled',true);
            jQuery("#processedOptionNo" + optionId).attr('disabled',true);
            var withlink = jQuery("#resumeFile"+ optionId).html();
            var withoutlink = jQuery(withlink).html();
            jQuery("#resumeFile"+optionId).html("").append(withoutlink);
            jQuery("#inputHidden1").val(optionId);
            jQuery("#inputHidden2").val(optionAnswer);
            jQuery("#hiddenForm").submit();
        }
    }
}

隐藏表单和 PHP:

<?php
if (isset($_POST['optionAnswer']) && $_POST['optionAnswer']){
    $optionId = $_POST['optionId'];
    $optionAnswer = $_POST['optionAnswer'];
    $queryOptionId = $wpdb->query($wpdb->prepare("UPDATE resume_databank SET process_resume = '$optionAnswer' WHERE id = %d", $optionId));
}
?>

<form id='hiddenForm' method='POST' action=''>
    <input type="hidden" id="inputHidden1" name="optionId" />
    <input type="hidden" id="inputHidden2" name="optionAnswer" />
</form>

您不想通过简单地将条件移出单选按钮字段来使其变得更容易和易于管理吗？创建 2 个变量并根据某些条件为它们分配值不会花费您太多成本，而且会让事情变得更加清晰。在这里，在回显任何内容之前尝试只创建 2 个变量: $checkYes 和 $checkNo 。然后我们检查是否 $result_position[$i]->process_resume=="Yes"在这种情况下，我们将“checked”分配给 $checkYes 变量。我们对 NO 做了同样的事情。然后，我们在适当的位置添加了 $checkYes 或 $checkNo...

    <?php
        // BE SURE THAT BOTH THE VARIABLES & CONDITIONAL STATEMENTS EXIST
        // WITHIN YOUR LOOP... PREFERABLLY AT THE BEGINNING OF THE LOOP.
        // OTHERWISE; $i HAS NO MEANING TO THE CONDITIONAL STATEMENTS BELOW.
        // CREATE THE $checkYes & $checkNo VARIABLES + INITIALIZE THEM TO EMPTY STRINGS
        $checkYes    = "";
        $checkNo     = "";
        // NEXT ASSIGN "checked" TO THE $checkYes OR $checkNo VARAIBLE
        // IF ANY OF THE CONDITIONS BELOW IS SATISFIED...
        // WE'LL USE THESE VARIABLES BELOW: WITHIN THE RADIO BUTTONS SECTION
        if($result_position[$i]->process_resume=="No"){
            $checkNo  = "checked"; 
        }
        if($result_position[$i]->process_resume=="Yes"){
            // TO DISABLE ALL RADIO BUTTONS WITH A "YES" VALUE;
            // SIMPLE ADD "disabled" TO THE $checkYes STRING LIKE SO:::
            $checkYes = "checked  disabled";
            $checkNo  = "disabled"; 
        }

        echo '<td id="submit_time">'    . $result_position[$i]->submit_time     . '</td>';
        echo '<td id="last_name">'      . $result_position[$i]->last_name       . '</td>';
        echo '<td id="first_name">'     . $result_position[$i]->first_name      . '</td>';
        echo '<td id="middle_name">'    . $result_position[$i]->middle_name     . '</td>';
        echo '<td id="mobile_number">'  . $result_position[$i]->mobile_number   . '</td>';
        echo '<td id="email">'          . $result_position[$i]->email           . '</td>';
        echo '<td id="location">'       . $result_position[$i]->location        . '</td>';
        echo '<td id="position">'       . $result_position[$i]->position        . '</td>';
        echo '<td id="message">'        . $result_position[$i]->message         . '</td>';
        echo '<td id="resumeFile'       . $optionId . '"><a href='              . wp_get_attachment_url($result_position[$i]->attachment_resume_id) . '>Download Resume</a></td>';
        echo '<td id="radioOption><label for="Yes">Yes</label>

    <input type="radio" id="processedOptionYes'.$optionId.'" name="processedOption_' . $optionId . '" ' . $checkYes . ' value="Yes" onclick="proccessedCheck('.$optionId.',\'Yes\')"/>
