我正在加载一个带有选中和未选中框的PHP页面。提交表单并使用library(shiny)
ui <- fluidPage(
tabsetPanel(
tabPanel("one", textOutput('text')),
tabPanel("two",
uiOutput('select'))
)
)
server <- function(input, output, session) {
c <- reactive({
list("A", "B", "C")
})
d <- reactiveValues(choice = "A")
output$select <- renderUI({
selectInput(
inputId = "choice",
label = "Select input",
choices = c(),
selected = 1
)
})
observe({
req(input$choice)
d$choice <- input$choice
})
output$text <- renderText(
d$choice
)
}
shinyApp(ui, server)
方法获取数组的值时，即使选中了复选框，$_POST数组中每个复选框的值为“ 0”。
我知道我的代码存在插值问题。请不要对此发表评论。
isReadOnly[]这是<?php
$departmentID = $_GET['departmentID'];
$departID = $_POST['employees'];
$isReadOnly = $_POST['isReadOnly'];
if(isset($_POST['update']))
{
for ($i=0; $i<sizeof ($departID);$i++) {
$result3 = mysqli_query($db,"INSERT INTO userDepartment (userID, departmentID,isReadOnly) SELECT userID,'" . $departID[$i] . "'," . $isReadOnly[$i] . " FROM users where userID='$id'");
}
}
?>
SOME OTHER CODE...
<?php
$sql = "SELECT d.departmentID, d.departmentName, ud.departmentID, ud.isReadOnly FROM department d LEFT JOIN userDepartment ud ON ud.departmentID = d.departmentID AND ud.userID = '$id' ORDER BY d.departmentID ASC";
$result = mysqli_query($db,$sql);
$c = 0;
echo "<div class='manageUserTable'>
<table><th colspan='2'>Budget</th><th>Is Read Only</th>\n";
while($row = mysqli_fetch_array($result)){
$departID = $row[2];
$checkedDep = ($row[0] == $departID) ? 'checked="checked"':'';
$checkedreadOnly = ($row[3] == '1') ? 'checked="checked"':'';
echo "<tr>
<td class='check'><input type='checkbox' name='employees[$c]' value='".$row['0']. "' " . $checkedDep . "'></td>
<td class='depName'>".$row['1']."</td>
<td class='check'><input type='hidden' name='isReadOnly[$c]' value='0'><input type='checkbox' name='isReadOnly[$c]' value='".$row['3']. "' " . $checkedreadOnly . "'>
</tr>";
$c++;
}
echo "</table></div>\n";
?>
中的var_dump：
$_POST array(5) { ["username"]=> string(15) "bobby.zimmerman" ["employees"]=> array(1) { [0]=> string(1) "1" } ["isReadOnly"]=> array(29) { [0]=> string(1) "0" [1]=> string(1) "0" [2]=> string(1) "0" [3]=> string(1) "0" [4]=> string(1) "0" [5]=> string(1) "0" [6]=> string(1) "0" [7]=> string(1) "0" [8]=> string(1) "0" [9]=> string(1) "0" [10]=> string(1) "0" [11]=> string(1) "0" [12]=> string(1) "0" [13]=> string(1) "0" [14]=> string(1) "0" [15]=> string(1) "0" [16]=> string(1) "0" [17]=> string(1) "0" [18]=> string(1) "0" [19]=> string(1) "0" [20]=> string(1) "0" [21]=> string(1) "0" [22]=> string(1) "0" [23]=> string(1) "0" [24]=> string(1) "0" [25]=> string(1) "0" [26]=> string(1) "0" [27]=> string(1) "0" [28]=> string(1) "0" } ["id"]=> string(2) "82" ["update"]=> string(14) "Update Account" }
的索引0在该输出中应该为“ 1”。
答案 0 :(得分：0)
在这一行：<input type='checkbox' name='isReadOnly[$c]' value='".$row['3']. "' " . $checkedreadOnly . "'>，value='".$row['3']. "'应该是value='1'。
