在Perfex CRM（CodeIgniter）中实现单选按钮值存入数据库求助

Your current radio button code has several issues preventing it from working like the dropdown. Here's the corrected implementation, along with explanations of the fixes:

Corrected Radio Button Code #

First, keep your existing $accessability array (it's reusable for the radio buttons):

$accessability = [
    0 => ["id" => "Yes", "name" => _l("Yes")],
    1 => ["id" => "No", "name" => _l("No")],
    2 => ["id" => "Not Applicable", "name" => _l("Not Applicable")]
];

Then replace your radio button HTML with this dynamic, clean version:

<div class="col-md-12">                           
    <div class="mtop10">
        <span>ACCESSABILITY TO PROPERTY WAS CLEAR</span>
        <?php foreach ($accessability as $option): ?>
            <div class="radio radio-primary radio-inline">
                <input type="radio" 
                       value="<?php echo esc($option['id']); ?>" 
                       id="accessability_<?php echo esc($option['id']); ?>" 
                       name="accessability" 
                       <?php echo isset($disscussion->accessability) && $disscussion->accessability == $option['id'] ? 'checked' : ''; ?>>
                <label for="accessability_<?php echo esc($option['id']); ?>"><?php echo $option['name']; ?></label>
            </div>
        <?php endforeach; ?>
    </div>
</div>

Key Fixes Explained #

• Shared Name Attribute: All radio buttons use name="accessability" (matching your dropdown's name). This groups them together, ensuring only one can be selected at a time.
• Matching Values: Each radio's value matches the dropdown's id values ("Yes", "No", "Not Applicable"), so the saved data is consistent with your existing dropdown logic.
• Valid Checked Condition: The PHP checks if the saved value ($disscussion->accessability) matches the radio's value, adding the checked attribute when true.
• Unique IDs: Each radio gets a unique ID (e.g., accessability_Yes) so the <label> elements correctly link to their inputs.
• XSS Protection: Uses CodeIgniter's esc() function to sanitize output, preventing cross-site scripting vulnerabilities.

Why Your Original Code Failed #

• Non-Matching Names: Your radios had different names ("Yes" and "No"), so they weren't grouped—selecting one didn't deselect the other, and the controller wouldn't receive a consistent accessability value.
• Incorrect Values: Both radios used value="1", which doesn't match your dropdown's values, leading to wrong data being saved.
• Broken PHP Syntax: The checked condition in your original code was incomplete (missing the if body and proper comparison), so it never set the checked attribute.

Save Logic Note #

Since the radio buttons use the same name="accessability" as your dropdown, you don't need to change any backend save logic—your existing CodeIgniter controller code that handles the dropdown submission will work for the radios too.
