我正在构建一个小的 php 文件。我需要选择随机复选框。复选框在某些条件下从表格中拉出时是动态的。
如果我可以随机选择几个复选框，请告诉我，如果我从 mysql 表中获得 100 个结果，则需要选择 10 个随机复选框。
<?php
$n1=0;
$rambo = strip_tags(@$_POST["assoocc"]);
$r11 = strip_tags(@$_POST["ccdate"]);
$r12 = strip_tags(@$_POST["rrdate"]);
$submit = @$_POST["submit22"];
?>
<body><div>
<form action="selectedcc.php" method="post">
<center> <table width="600" border="1" cellpadding="1" cellspacing="1">
<tr>
<th colspan="3"> Total cases for QA</th>
<th colspan="2"><?php
$ticket=mysql_query("SELECT * FROM us_tickets where (status='Resolved') and (associate='$rambo') and (resolve_date >='$r11') and (resolve_date <='$r12')");
$m1=mysql_num_rows($ticket);
echo "$m1";
?></th>
<th colspan="2"><select name="assoocc1" class="form-control" id="sel1" style="width: 150px;" >
<?php echo "<option value=$rambo selected>".$rambo."</option>";
?>
</select></th>
<th colspan="1"><input type="submit" name="sub" value="Submit For QA "/></th>
</tr>
<tr>
<th>Select Here</th>
<th>Case Id</th>
<th>Task</th>
<th>Number of ASINs</th>
<th>SLA Details</th>
<th>Create date</th>
<th>Resolved date</th>
<th>Rootcause</th></tr>
<?php
if ($submit)
{
if ($rambo&&$r11&&$r12)
{
if ($r11<$r12)
{
$ticket=mysql_query("SELECT * FROM us_tickets where (status='Resolved') and (associate='$rambo') and (resolve_date >='$r11') and (resolve_date <='$r12')");
$m1=mysql_num_rows($ticket);
for($k=0; $k<$m1; $k++)
{
$caseid1 = $task1 = $asin1 = $sla1 = $associate1 = $quer = "";
${"caseid".$k}=mysql_result($ticket,$k, "case_id");
${"task".$k}=mysql_result($ticket,$k, "sub_issue");

最佳答案
从Generating UNIQUE Random Numbers within a range - PHP中获取随机函数UniqueRandomNumbersWithinRange
<?php
function UniqueRandomNumbersWithinRange($min, $max, $quantity) {
$numbers = range($min, $max);
shuffle($numbers);
$arr = array_slice($numbers, 0, $quantity);
sort($arr);
return $arr;
}
$chkArr = array();
$rand = UniqueRandomNumbersWithinRange(0, 100, 10);
$rIdx = 0;
for($k=0; $k<100; $k++){
$caseid1 = $task1 = $asin1 = $sla1 = $associate1 = $quer = "";
${"caseid".$k}=mysql_result($ticket,$k, "case_id");
${"task".$k}=mysql_result($ticket,$k, "sub_issue");
${"asin".$k}=mysql_result($ticket,$k, "asin");
${"vendor_credit".$k}=mysql_result($ticket,$k, "vendor_credit");
${"create_date".$k}=mysql_result($ticket,$k, "create_date");
${"resolve_date".$k}=mysql_result($ticket,$k, "resolve_date");
${"root_cause".$k}=mysql_result($ticket,$k, "root_cause");
${"associate".$k}=mysql_result($ticket,$k, "associate");
$chk = '';
if( in_array($k, $rand) )
$chk = "checked";
array_push($chkArr, "<tr>"."<th>"."<input type='checkbox' ".$chk ." value='${'caseid'.$k}' name='checkboxvar[]'>"."</th>"."<th>".${'caseid'.$k}."</th>"."<th>".${'task'.$k}."</th>"."<th>".${'asin'.$k}."</th>"."<th>".${'vendor_credit'.$k}."</th>"."<th>".${'create_date'.$k}."</th>"."<th>".${'resolve_date'.$k}."</th>"."<th>".${'root_cause'.$k}."</th>"."</tr>");
}
echo implode($chkArr);
?>
