告诉我有更好的方法可以将这些复选框转换为JSON

json arrays php

Ryan · 技术社区 · 14 年前

我正在做一个表格,让人们选择他们喜欢的联系方式。除此之外,该表单包含9个复选框(3组3个),我正试图将其作为JSON存储在我的数据库中。

这是表格的相关部分…

<h1 style="padding-top:25px;">Communication Preferences</h1><hr />
<div class="onethird contactprefs" style="width: 28%">
    <h4>Preferred Method</h4>
    <p>From time to time, we might need to contact you regarding our service.  Which mode of contact would you prefer?</p>
    <p>
    <input type="checkbox" name="preferred[]" value="p" style="display: inline;" />Phone <!-- make these tooltips -->
    <br />
    <input type="checkbox" name="preferred[]" value="e" style="display: inline;" checked />Email
    <br />
    <input type="checkbox" name="preferred[]" value="s" style="display: inline;" />SMS
    </p>
</div>

<div class="onethird contactprefs" style="width: 28%; border-left: solid 1px #cdcdcd; border-right: solid 1px #cdcdcd; padding-left: 18px; padding-right: 15px;">
    <h4>Weather Delays</h4>
    <p>We don't mess with Mother Nature, and sometimes she forces us to cancel service.  If that happens, how should we inform you?</p>
    <p>
    <input type="checkbox" name="weather[]" value="p" style="display: inline;" />Phone
    <br />
    <input type="checkbox" name="weather[]" value="e" style="display: inline;" checked />Email
    <br />
    <input type="checkbox" name="weather[]" value="s" style="display: inline;" />SMS
    </p>
</div>

<div class="onethird contactprefs" style="width: 28%">
    <h4>Holiday Reminders</h4>
    <p>If you'd like us to send you reminders about interruptions in service due to holidays, just choose your preferred method below.</p>
    <p>
    <input type="checkbox" name="holiday[]" value="p" style="display: inline;" />Phone
    <br />
    <input type="checkbox" name="holiday[]" value="e" style="display: inline;" checked />Email
    <br />
    <input type="checkbox" name="holiday[]" value="s" style="display: inline;" />SMS
    </p>

</div>

 <!-- end contact preferences -->

正如我提到的,我需要从这些复选框中获取数据,并将其转换为格式良好的JSON字符串。

这是我正在做的,但看起来很乱。告诉我有更好的方法…

/* THERE MUST BE A BETTER WAY TO DO THIS */
// get the preferred data
$preferred = $this->input->post('preferred');

if(in_array('p',$preferred)){
    $pref['p'] = 1;
}else{ $pref['p'] = 0;}

if(in_array('e',$preferred)){
    $pref['e'] = 1;
}else{ $pref['e'] = 0;}

if(in_array('s',$preferred)){
    $pref['s'] = 1;
}else{ $pref['s'] = 0;}

// get the weather data
$weather = $this->input->post('weather');

if(in_array('p',$weather)){
    $wea['p'] = 1;
}else{ $wea['p'] = 0;}

if(in_array('e',$weather)){
    $wea['e'] = 1;
}else{ $wea['e'] = 0;}

if(in_array('s',$weather)){
    $wea['s'] = 1;
}else{ $wea['s'] = 0;}

// get the holiday data
$holiday = $this->input->post('holiday');

if(in_array('p',$holiday)){
    $hol['p'] = 1;
}else{ $hol['p'] = 0;}

if(in_array('e',$holiday)){
    $hol['e'] = 1;
}else{ $hol['e'] = 0;}

if(in_array('s',$holiday)){
    $hol['s'] = 1;
}else{ $hol['s'] = 0;}

$contact_prefs = array('preferred' => $pref,'weather' => $wea,'holiday' => $hol);
$contact_prefs = json_encode($contact_prefs);

提前感谢您的洞察力。

一个让它更自动的想法( 未经测试的 ):

$contact_prefs = array();
$groups = array('preferred', 'weather', 'holiday'); // checkbox groups

foreach($groups as $group) {
    $preferences = array('p' => 0, 'e' => 0, 's' => 0); // create default array
    $values = $this->input->post($group); // get the checked values for a group
    foreach($values as $value) {
        $preferences[$value] = 1; // if box is checked, set value to 1
    }
    $contact_prefs[$group] = $preferences;
}

$contact_prefs = json_encode($contact_prefs);

当然,这只在三个复选框组具有相同值时才有效。
