如何获得$ _POST的函数值

时间：2012-08-12 03:50:39

标签： php

所以我试图获取这个函数，这是一个表单的状态下拉选择，给我在另一个文件中使用$ _POST提交时所选内容的值，事情是我真的不知道如何使用'name ='发送的参数。

这是我的代码

<?php
    function state_select ($name,$full_state,$selected = '') {

  $state_list = array("AL|Alabama","AK|Alaska","AZ|Arizona", "AR|Arkansas", "CA|California", "CO|Colorado", "CT|Connecticut", "DE|Delaware", "DC|Washington D.C.", "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", "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");

  ?>
  <select name=<?=$name;?> id="state" ><?
    foreach ($state_list as $s) {
        $values = explode("|",$s);
        ?><option value="<?=$values[0];?>" <?
                if($selected == $values[0]) { ?>SELECTED<? }
                ?>>
                <? if($full_state) { ?><?=$values[1];?><? } else { ?><?=$values[0];?><? } ?></option><?
    }
  ?></select><?
}
?>


<span class="InputDiscription">State: </span><div class="InputInner"><?=state_select('state',false,'AL'); ?></div><!----- END .InputInner ---------->
<?php
 $setError=$_GET['seterror']; 
if($setError == 1){
    echo "<span class='errorMsg'>*Required</span>";
    }
else
    echo "<span>*</span>"; 

?>

谢谢！

这将提交表单，你需要添加一个表单元素并使用select元素上添加的onchange事件提交它，我希望这有帮助

<html>
<head>  
<script type="text/javascript">
function submitform(){
    document.forms["theform"].submit();

  $state_list = array("AL|Alabama","AK|Alaska","AZ|Arizona", "AR|Arkansas", "CA|California", "CO|Colorado", "CT|Connecticut", "DE|Delaware", "DC|Washington D.C.", "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", "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");

这个怎么样？和其他php文件一起使用$ selectvalue = $ _ POST ['hiddenfield'] 

<html>
<head>  
<script type="text/javascript">
function submitform(){
    // Get the index of selected item
    var list = document.getElementById('state');
    var INDEX = list.selectedIndex;
    document.getElementById("hiddenfield").value=list[INDEX].value;

    //Submit the form
    document.forms["theform"].submit();
}
</script>
</head>
<body>

<form action="otherfile.php" method="post" name="theform">
<?php
    function state_select ($name,$full_state,$selected = '') {

  $state_list = array("AL|Alabama","AK|Alaska","AZ|Arizona", "AR|Arkansas", "CA|California", "CO|Colorado", "CT|Connecticut", "DE|Delaware", "DC|Washington D.C.", "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", "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");

  ?>
  <select name=<?=$name;?> id="state" onchange="submitform()"><?
    foreach ($state_list as $s) {
        $values = explode("|",$s);
        ?><option value="<?=$values[0];?>" <?
                if($selected == $values[0]) { ?>SELECTED<? }
                ?>>
                <? if($full_state) { ?><?=$values[1];?><? } else { ?><?=$values[0];?><? } ?></option><?
    }
  ?></select><?
}
?>


<span class="InputDiscription">State: </span><div class="InputInner"><?=state_select('state',false,'AL'); ?></div><!----- END .InputInner ---------->
<?php
 $setError=$_GET['seterror']; 
if($setError == 1){
    echo "<span class='errorMsg'>*Required</span>";
    }
else
    echo "<span>*</span>"; 

?>
<input type="hidden" id="hiddenfield" name="hiddenfield" value="">
</form>
</body>
</html>

＆GT;

并在otherfile.php中 输入这个，你可以得到值

<?php
echo "hiddenfield=".$_POST['hiddenfield'];
?>
