我已经生成了一个表单,其中一些字段是多选的。这些值是从 foreach 生成的(由于所需的格式):
echo '<select name="data[formdata]['.$question['PrPageQuestion']['ID'].']" id="formdata'.$question['PrPageQuestion']['ID'].'" multiple="multiple">';
foreach($contacts as $contact):
echo '<option value="'.$contact['PrDataContact']['ID'].'">'.$contact['PrDataContact']['Name'].' ('.$contact['PrDataContact']['Email'].')</option>';
endforeach;
echo '</select>';
但是,当我选择多个并提交表单时,我运行调试时只传递了一个值,而不是预期的字符串。
html输出为:
<select name="data[formdata][2]" id="formdata2" multiple="multiple">
<option value="13">A Contact (a.contact@email.com)</option>
<option value="14">A. Nother-Contact (a.n.contact@email.com)</option>
<option value="15">A. New. Contact (anc@email.com)</option>
<option value="17">New Conti (new@conti.com)</option>
</select>
var_dump 的输出是:
array(2) {
["_method"]=> string(4)
"POST" ["data"]=> array(1) {
["formdata"]=> array(8) {
//other data was here
[1]=> string(1) "1"
[2]=> string(2) "15"
[3]=> string(1) "4"
[4]=> string(0) ""
}
}
}
