我有公司数据库，每个公司只能运送到一定数量的州。我用一个表单来管理它们，该表单向MySQL字段发送所有状态(用逗号分隔每个状态)。
我在解析字符串时遇到了麻烦，所以当页面加载
时，它会检查带有状态属性的框$check ="NY,CA,FL";
function state_list($check) {
$arr = array('AL'=>"Alabama",'AK'=>"Alaska",'AZ'=>"Arizona",'AR'=>"Arkansas",'CA'=>"California",'CO'=>"Colorado",'CT'=>"Connecticut",'DE'=>"Delaware",'DC'=>"DC",'FL'=>"Florida",'GA'=>"Georgia",'HI'=>"Hawaii",'ID'=>"Idaho",'IL'=>"Illinois", 'IN'=>"Indiana", 'IA'=>"Iowa", 'KS'=>"Kansas",'KY'=>"Kentucky",'LA'=>"Louisiana",'ME'=>"Maine",'MD'=>"Maryland", 'MA'=>"Massachusetts",'MI'=>"Michigan",'MN'=>"Minnesota",'MS'=>"Mississippi",'MO'=>"Missouri",'MT'=>"Montana",'NE'=>"Nebraska",'NV'=>"Nevada",'NH'=>"New Hampshire",'NJ'=>"New Jersey",'NM'=>"New Mexico",'NY'=>"New York",'NC'=>"North Carolina",'ND'=>"North Dakota",'OH'=>"Ohio",'OK'=>"Oklahoma", 'OR'=>"Oregon",'PA'=>"Pennsylvania",'PR'=>"Puerto Rico ",'RI'=>"Rhode Island",'SC'=>"South Carolina",'SD'=>"South Dakota",'TN'=>"Tennessee",'TX'=>"Texas",'UT'=>"Utah",'VT'=>"Vermont",'VA'=>"Virginia",'WA'=>"Washington",'WV'=>"West Virginia",'WI'=>"Wisconsin",'WY'=>"Wyoming");
foreach($arr as $k => $v){
$checked = ($check == $k) ? ' checked="yes"' : '';
echo '<li><input class="checkStates" name="states" type="checkbox" value="'.$k.'"'.$checked.'>'.$v.'</li>';
}
}
如果$check是逗号分隔的，您可以将字符串展开并将其转换为数组，然后在for循环中，只需检查状态是否在数组中。
$check ="NY,CA,FL";
$arr = array('AL'=>"Alabama",'AK'=>"Alaska",'AZ'=>"Arizona",'AR'=>"Arkansas",'CA'=>"California",'CO'=>"Colorado",'CT'=>"Connecticut",'DE'=>"Delaware",'DC'=>"DC",'FL'=>"Florida",'GA'=>"Georgia",'HI'=>"Hawaii",'ID'=>"Idaho",'IL'=>"Illinois", 'IN'=>"Indiana", 'IA'=>"Iowa", 'KS'=>"Kansas",'KY'=>"Kentucky",'LA'=>"Louisiana",'ME'=>"Maine",'MD'=>"Maryland", 'MA'=>"Massachusetts",'MI'=>"Michigan",'MN'=>"Minnesota",'MS'=>"Mississippi",'MO'=>"Missouri",'MT'=>"Montana",'NE'=>"Nebraska",'NV'=>"Nevada",'NH'=>"New Hampshire",'NJ'=>"New Jersey",'NM'=>"New Mexico",'NY'=>"New York",'NC'=>"North Carolina",'ND'=>"North Dakota",'OH'=>"Ohio",'OK'=>"Oklahoma", 'OR'=>"Oregon",'PA'=>"Pennsylvania",'PR'=>"Puerto Rico ",'RI'=>"Rhode Island",'SC'=>"South Carolina",'SD'=>"South Dakota",'TN'=>"Tennessee",'TX'=>"Texas",'UT'=>"Utah",'VT'=>"Vermont",'VA'=>"Virginia",'WA'=>"Washington",'WV'=>"West Virginia",'WI'=>"Wisconsin",'WY'=>"Wyoming");
$states = explode(',', $check);
foreach($arr as $k => $v){
$checked = in_array($k, $states) ? ' checked="yes"' : '';
echo '<li><input class="checkStates" name="states" type="checkbox" value="'.$k.'"'.$checked.'>'.$v.'</li>';
}
我想这和你的比较有关。确保$check是大写的。如果它通过了，那么它一定与传入的$check值有关。
编辑:你需要做的是…
$ary = explode(",", $check);
foreach($arr as $k => $v) {
$checked = (in_array($k, $ary)) ? ' checked="yes"' : '';
echo '<li><input class="checkStates" name="states" type="checkbox" value="'.$k.'"'.$checked.'>'.$v.'</li>';
}
